I guess I wasn't clear my bad. I have put in another wiring harness up front. I have the nss wire 3 points. My car is a 71 scamp I cannot find where to plug in the middle plug looks kinda like a rounded triangle. I have been told firewall or under dash but I cannot find anything to plug it into. Does anyone have a pic of where to look or what I am looking for? Thanks guys and I agree especially as the track will send me home without it I understand.
