Passenger side light assy is making me nuts. Lights on, directional works put car in reverse and the back up light on that side goes out when you put the directional on. I have changed bulbs ,cleaned the brass contacts inside the light assy., changed relays. Could it be a dirty fuse or might I need another light assy on that side? Anyone know of a used one around? All theories appreciated... Bob

Thanks Paul for pointing me in the right direction . I'll be adding the ground tomorrow.

 

Took maybe twenty minutes. Works as advertised. Thanks all...
