Hello again So heres the deal (NO Ground to low beams) I went out with my multimeter in hand today and found that the headlights have no ground on the lowbeams now my most logical thought was to just splice in a new ground, so I figured the highbeam ground was very close so why not use that (Right?) Wrong I was then suprised to learn that when I spliced into the high beam ground wire and tried the lowbeams all the headlights now came on high and low beams . So I figured that the grounds must run through a relay of some sort at this point so I disconnected the splice I made and it is back to a no headlight on low beams. But here is my question can I just run a new ground wire spliced into the lowbeam ground wire and ground it to the body of truck (because lowbeams will work when grounded to the body I tested it and yes they worked as they should (but I thought the wire I was using got a lil hot so I did not leave it connected to long). Or are these headlights designed by GM to be grounded only through a relay to avoid burnout? Or can I go ahaed and just use the spliced in ground and use the low beams safely the way the new ground is? Thanks again for all who respond
