Hey folks! Got a question and some trivia for you. What are the differences between the 1967 early and late versions of the under dash wiring harnesses?
What, nobodies got even a guess? 
XR 7 or standard?
Dual brake (emergency and differential valve) warning lite
Standard
OK, Joe is new and not quite dialed into the whole forum thing so I will follow up for him. He and Andrew were working on this and documented the major difference between early and late, here is the link.
