i have a 77 volare 225\6 i've been rebuilding pretty much from scratch. i tracked down the wiring harness to the nss, but i cannot figure out where to plug it into the rest of the harness. i've looked at a couple wiring diagrams and i just cannot figure it out. i must sound retarded, but this is the last thing i need to hook up so i can have key ignition/reverse lights/gauges.
