How do you install

1968 Xr7

Relay - Turn Signal - Solid State - K-5

I removed the old relay. Not too tough. However, installing the new relay is much more difficult. Only room for 1 hand, on my back/side while looking up. Hand block’s view of relay and hole alignment and the light source. I spent hours trying to finagle a way to get multiple socket combos to work. No luck. Anyone who has done this job, have any tips?

Identify the relay you are working on and Pictures would help.
