Hi can anyone help. Fitted new rear loom to my 67 mustang. The left side, drivers side works Fine, front and back. Passenger side, right, well only flash at front. Doesn't seem to be any power going to the right side!!!!!. Please any help.
From the harness, there are the 2 wires that fit to the back of the bulb connector and then a black wire that fits to spade connector on the side of the bulb connector. Wired drivers side exactly the same and that works. Bulbs all good, checked them in the drivers side. Both front flashers work as well.
I meant on the harness itself, a ground eyelet by the trunk latch support uses a sheetmetal screw
other than that Im out of guesses
Break out the test light and see how far the power is getting.
