Hey folks. Looking for some help. I have been enlisted to help my sons girlfriend get her 83' truck running. It has a v-8 with what I think is a 360. There is a pink wire coming out of the wiring loom on the drivers side near the firewall and not connected to anything. The wire is about 18-24 inches in length and has about 1/2" of exposed copper sticking out of the end. When we connect this wire to 12v you can hear the distributor clicking and the truck will start and run. I know this wire should be connected to a switched power source but for the life of me I can't figure out what it should be tied into. Can someone please tell me what to connect this thing to. Better yet if you have a pic that shows how and where it ties into that would be great. Thanks
