just put my harness in,have power to fuse box but no power to anything like wipers ,heater,and only outside headlights work,go out when hit dimmer switch and its new,only things working is overhead light,starter,and dash high beam light,am i missing a ground or what?horn relay went to smoke so i bypassed it, any help? email@example.com
Not sure why this is in the hall of fame section? should be moved. Without getting super deep into this I would say your horn relay comment is probably a hint as that is a major power source. Harold b's site has all the 68 manuals including wiring diagrams in the library section. https://www.firebird400ho.com/ get your volt meter out and start following from the source outward.
was thinking on the same line,ordered a horn relay today,thought i had it in forums this is the worst site i ever worked with,but thanks for the info,i have always been chevy man,have a 66 L-79 nova and a 67 SS, just got this rust free bird and have it about 90 percent,but piss me off it will go to scrap yard, took a 69 camaro there a couple years back for about same reason,nothing is a simple as these old cars and be dam if one will win
Also don't forget you could be having multiple issues going on. If after getting things sorted out you find the headlights still go dark when put on high beams and verifying your new Chinese switch is working properly don't forget the low beams switch to a different filament when on high beam and yours wouldn't be the first car after sitting around forever to have that many burnt filaments.
