    Go buy one of the adapter plugs from the local auto store. $15, and you will save yourself and any PO wiring headaches, and time. It's foolproof, and besides soldering and sealing wire splices if you went that route, the right way to do it. It just plugs right into your tail light wiring harness. I'm pretty sure '83 was using weatherpack connectors at that time, as I think thats all the adapter "t's" fit.

    Why insist on counting when the ring gear has the tooth counts stamped in?

    Keith, Michael's right. Those are on the wiring diagram (which I happen to be studying, in my own wiring hell...) [​IMG]

    Unless you drive a dodge, in which case, God help you on the colors.
