headlight wiring conformation
Everything I have seen shows the attached hi/low stock plug wired as in the
drawing, but on my 87 z28 the ground and high beam is swapped. Could someone confirm whether mine is wired correctly or not?
Thanks

Re: headlight wiring conformation
Grab your test light or volt meter.
Ground to a bolt, probe the one you think is high-beam while your high-beams are on.
Question answered.
I have the adapters from Susquehanna somewhere for visual reference but I did the switch latter on . . .

Re: headlight wiring conformation
I did the probe already and found that my ground and high beam is swapped as compared to the stock 4656 as shown in the drawing.
