Update:
My question is - if I bolt into a pre-existing hole in the truck frame, (recent F-350) with a new, stainless steel bolt…. would the frames coating (anodized?) stop it from being a good ground?
see pic of my attempt at grounding (below)
I was advised to avoid drilling new holes into the truck frame… just use pre-existing holes.
so i got the trailer light kit (Blazer C6421 Trailer Light Kit) and I spoke with Blazer previously…..
and they said: I HAVE to ground the white ground wire to the truck frame.
I asked “could I just wire the white ground wire to the 4 pin flat trailer lights plug?” and they said it likely will *not* work…. and i’d need at least a 12 gauge wire … but it is better to ground to the frame.
So I wired everything up today (very simple with the kit) and plugged in… and tested the lights and they did not work at all. Never lit up. Yes the truck lights work fine, and i know that the 4 pin flat plug *is* working fine. (I tested it with something else)
I suspect the anodizing on the frame is the issue. Yes? No?
and if i have to drill a hole…. i was advised to drill into the hitch assembly, *not* the truck frame.
thanks for any guidance.
