I have pulled my dash out for the first time in my 1968 Mustang coupe (c4). I'm a beginner mechanic and have no idea what this black wire is or where it goes. I removed my instrument panel to replace the dim dash lights with blue LED lights. When I tried to put the dash back in, the dash lights do not work and. Ow my car does when I pull the lights out, turn them on.
i do see a similar black wire female end that connects to the pull light module, but I'm not sure if these belong together.
