Today while at the yard I found a 70 -72 monte carlo with power locks, windows, and tilt wheel.My question is on the power lock harness there is a very small plug on each side near the kick panel.It has one orange and one yellow wire.What are these for.Could it be lights, or door buzzer,what? I know you guys are going to say i'm crazy,but I already have the windows and tilt, so I left those.I plan on going back when I get paid for those items.If anyone could help me out on the small plug that would be great. Also if anyone is interested in the windows or tilt let me know.will the regulators work on chevelles. Whats the going price for complete window set up?
