The car is a full build. Rebuilt trans, new engine ect. Yes its a 3 pin, two for reverse lights and the other is the nss. It wasn't working when I fish went to fire the car 2 months ago. Bought one from napa that broke right away. Got another that didn't work out of the box. Messed with the original and got it working. Now I think its failing again . Might be interested in a good used one, I'll let you know.
