Thanks. Just what I was looking for. Question though, not much electrical knowledge. My side marker pigtail only has one wire and no ground wire on the housing?
That is correct. In '68, the round side markers in the fenders, and the quarter panels only had one hot wire. the light housings themselves are grounded to the body (fender, quarter panel)
but, whats confusing to me is, in the picture you provided, that is the drivers side fender marker? and you have 2 wires coming from/to it? if you look at my picture, my side markers are powered with 1 wire...
