I have been searching on the internet for a 69 thunderbird directional signal wiring diagram but I have not been able to find one, however the thunderbird site 1969 sequential flasher unit interior pics - Vintage Thunderbird Club International shows the internals of a 69 thunderbird sequencer that has the same board number as the 69 cougars. So assuming that they are indeed the same, then this information should help you out.
This is by design as the 442 (left)and 445 (right) circuit on the harness side provides not only input to the sequencer as well as power to the left inner turn signal.
Did your sequentials work without the 5 W cornering lights? If they work with the stock lights and only have a problem with the cornering lights, then you will need to wire in a resistor and a relay and use the 448 and 449 circuits to trigger the relay and let the relay power the lights separately.
You can also test the sequencer itself, see my previous posts in this thread to SwedishCougar.
BTW, I am working on a 63 thunderbird roadster although the 63 has the round taillights.
Searched the internet and havent found a solution to my issue yet. Left everything works great. Front back, brakes, running, all good. right side, front turn signal works, side indicator works, dash indicator works, not rear right turn signalā¦ Right running lights work fine, no right brake lights. So in short, got everything but right rear turn lights ans right rear brake lights
Hello!!
I have placed 12 volt on No. 442 and 448 wires on the sequencer to see if the left inner and left outer taillights sequence.
It is just the middle lamp that light up so I guess that electronics are broken so I have to email VCCC and order a new seqenser.
Is there anyone who knows if the old components on the seqenser board can be bought anymore.
Iāve been having issues with the left turn signal for years. Originally it only worked intermittently so I replaced the sequencer in trunk with the electronic version. This got everything working fine.
I noticed later that after about 20-25 flashes the right turn signal would stop. The right turn signal would not function for about 5 min and they work again but if I let it flash 20 or more times it would again stop working for about 5 min. I had the electronic sequencer replaced and it seemed to work. But about 6 months later the problem came back. After sitting at a long light with the left blinker on it would stop working after about 20 or more successive blinks and remain inoperable for about 5min.
Now the left turn signal does not operate at all. Tail lights work. Brake lights work. Emergency flasher works on right side. However, I get no left blinker or emergency flasher. The dash lights illuminate solid on each side and the turn signal stick stays in place both left and right. Iām thinking of replacing the turn signal switch with this http://www2.cougarpartscatalog.com/sm45f.html?attribs=76.
Does anyone know if this could be the root of my problem?
The board consists of 16 resistors, 11 diodes, 4 capacitors, 4 thyristors, 4 transistors and 1 proprietary transistor and of course the board. Everything except the proprietary transistor can be purchased at an electronics store. Open up your sequencer box and see if here are any burn marks or cracked solder joints. When you open the box and hold the board with the components facing you and the large capacitor at the bottom, the left outer light controller is on the far left with the left middle light controller next to it.
I have a question regarding my 1969 cougar, I am trying to keep it as original as possible and one of the problems I am running into is the rear tail lights, when lights themselves are turned on all 3 in the rear workā¦ when a turn signal is turned on, the left driver works fine while the right passenger only turns on 2 lightsā¦ when braking the left has 2 lights on while the right has 1 or 2 varrying. I know itās not the bulbs that are dead because as I mentioned, all lights function when the light switch is turned on, what could this be a result of?
Gabriel, it actually could be the bulbs that are bad, as they are dual filament. So when you press the brake the second filament lights making the bulb brighter. So you might have a āpartial failureā, where only one filament has burned out. You can pull out one of the bulbs that is not coming on during braking and take a close look. If you still arenāt sure, then swap that bulb with another one in the tail light that you know is working properly, then check them again.
Another thing to check is the grounding of each bulb socket. Give each bulb socket a few good back-and-forth twists to firmly seat the metal bulb socket against the metal of the tail panel.
Try those basic checks and then get back to us with your results. Weāll go from there.
Just recently acquired a 1968 Cougar and starting to trouble shoot the sequential lights so new to them.
What I have is lights that turn on at all four corners but do not flash. With the research I have done so far it could be the k7 relay under the dash but not sure.
The problem Iām having is that I canāt find that relay and it is definitely not clicking. Iāve looked behind the climate controls and ashtray but donāt see it. Canāt seem to find any actual pictures of the '68 location though Iāve checked out the links and pdfs.
Any pics or advice would be appreciated as I donāt want to drive it until fixed.
The 68 circuitry simplified the dash indicator circuits by eliminating the K5 and K6 relays utilized on the 67, by directly powering the dash lights via the turn signal switch. However this required the 68 K7 relay to provide low side (ground) switching to flash the dash indicators whereas the 67 K7 relay provides high side (power) switching.
Another difference between the two years is the connectors at the turn signal harness is rectangular for the 67 whereas the 68s use a semicircular connector. And the K8/K9 connectors are different since the 67 uses only 2 connectors and the 68 uses 4 connectors.
What do your turn signals do when you put them in left/right operations? Do the lights sequence once and then all stay lit?
Let me know if you need any additional information.
As I mentioned when I activate the turn signals they light on left and right but donāt flash. Rear appears to be on the middle light and doesnāt change or flash.
Am I right that the k7 relay needs to be replaced? Going to check again and look for the relay.
No the K7 only controls the flashing of the dash lights, the sequencer motor in the trunk controls the sequencing (and flashing) of the rear taillights. The K7 also requires that all 3 taillights and the front turn signal light (also controlled by the sequencer) to be operating correctly for the K7 to cause the dash lights to flash.
The Sequencer Motor is activated when you place the turn signal stalk in left/right mode as well as emergency mode. Do you have the original sequence in the trunk or is it a solid state sequencer? If you have the original sequencer, you should be able to hear it turning when in left/right or emergency mode. You can bench test the sequencer for the 68 as described in my writeup.
I have a problem with all my rear lights I am hoping someone can assist me with, I will go through stationary, brake, reverse, turn signal, and also hazards to get the best diagnosis. When stationary with lights on the left, 2 function the 3rd is dead. On the right only the center light turns on, the other 2 are dead. When braking the left 3 all turn on, and the right only the middle bulb turns on the other 2 are dead. Reverse lights do not function at all. Turning signals on the left all 3 function, on the right initially 2 functioned but now only 1 turns on, if the wire harness is wiggled while the turn signal is on the 2nd light flickers on and off. Hazards only the center light bulb turns on for both. I will try to diagram this below to help understand better

Hopefully this helps and hope to hear from everyone soon, this is my first car as I am 16 so I am semi limited on knowledge however I do plan to replace all the wiring down the line when I have more of an idea of what to do
My 69 has new solid state control in the trunk with LED bulbs. The battery is good alt. and voltage reg. are new. voltage at the battery is 14.5 when car is running. everything works good until I turn on the headlights. With lights on only the first bulb in sequence works front is okay. I also replaced the can under the dash with a new solid state one. any ideas
In this configuration Iād recommend you replace both the emergency flasher and turn signal flasher with the digital units. I had a similar issue which this cured.
Gabriel, the first thing to do is to verify that the bulbs are good. I notice that several never light up, and the system depends on good bulbs to pull the right amount of current to make the flashers work.
It is great to know that knowlegable people like you care about my old Cougar. I own mine since 1979, it was than, my very first car and I am quite attached to it. My wife thinks that it is totally irrational and I have to sayā¦ she is right !
My car is an early 1968 (it was produced with the C 289 ci engine, on april 3th of 1968). You probably guess my first question : Am I right to think that I need de 1968 K-5 /13A366 or is there a sliding ball with the fact that my car is of an early serie ?
On your forum, you talk about the LED lights some peolpe are using. I need to know more about the adjustment on your relay, since I have put in those plasma LED light that Don sells at WCCC.
I would also like to find out about the kind of time line you think we can expect the K-5 /13A366 unit in stock at WCCC ?
Iāve creeped around long enough on the interwebs.
I think itās time I beg for help. I know this topic has been beaten to death, but I canāt seem to find a similar problem so WCCC told me to post it here.
Problem: turn signals arenāt sequencing properly, even stranger, the hazards and front turn signals are tied into the middle on both sides, yet on mine, instead both the outers are the ones flashing. They arenāt swapped with the center bulb, wires arenāt long enough.
This is a 1968 Cougar.
Left signal: Left outer and front left flashing only, not sequencing.
Right signal: Right outer and front right flashing only, not sequencing.
Relay is powered, Cam is indeed moving and Iāve verified that each wire is sequencing properly with three individual test lights.
Where did you verify that each wire is sequencing properly with three individual test lights? At the output of the sequential motor, at the output of the K8/K9 relay or at the taillight connectors?
Assuming you measured this at the output of the sequencer, disconnect the K10 relay, do the outers still flash? They shouldnāt because the K10 output is only for the inner and outer lights. If your outers are still flashing, then you know that the inputs to the K8/K9 relay have been crossed somewhere in the harness.
Assuming you measured this at the output of the K8/K9 relay, this indicates a problem with the wiring harness from the k8/k9 relay to the taillights.
Assuming you measured this at the taillight bulb connectors, this indicates a grounding issue with the taillight sockets.
The fronts are supposed to flash with the middle taillight bulbs, so either someone has hacked the wires, or the K8/k9 inputs have been hacked or the fronts are working but the sequencing is fast enough that you perceive the fronts are tied to the outers when indeed they are activating with the center.
I would concentrate on fixing the taillights first and then determine if the fronts are an issue.
I checked it at D43 connector and let it blink away just to make sure itās working.
The old one was hacked pretty badly, so I bought a NOS one though itās from a 67 since it was a killer deal and itās pretty much the same thing but with different connectors. After reading the diagram I concluded that Green/red and green/blk needs to be swapped as well as orange/white and orange/red. I took a scan of the diagram between the two and the match up.
I went through the wiring harness and itās pretty much untouched.
Correct me if Iām wrong but the correct order from left to right is:
Green/Black, Green/Red, Green/Orange Orange/Blue, Orange/White, Orange/Red
If so, thatās correct on my vehicle then.
Iāve written your reply down and Iāll run down the whole list.
[quote]Correct me if Iām wrong but the correct order from left to right is:
Green/Black, Green/Red, Green/Orange Orange/Blue, Orange/White, Orange/Red[/quote]
This is correct for a 67 and a 68 however your diagram shows that you swapped the Green/Black and Green /Red (left center and left outer) and the Orange/white and Orange/Red (right center and right outer). So this explains why your front lights flash with your āoutersā.
The D43 connector is the output of the sequential motor, so you should test your K10 relay as again it connects/disconnects the inners and outers. The K10 should have power when the Hazards are off and should not have power when the hazards are on.
You can bypass the K10 relay. Unplug the connector at the K10 relay. Make 2 jumper wires (approx 6" long) with male ends on both sets of wire, 1 connecting the 436 and 436A (yellow to yellow) circuits and the other tying the 438 to 438A (yellow-black to yellow-black) circuits. This effectively ties the SQM output directly to the SEQ so that the inner and outer taillights function for turn signal operations AND HZWSW ON operations.
