I tested every pin in headlight harness and you’re right, I got not voltage to tie into high beams. Ended up using Aux 1 to trigger light bar which does work fine.
I have not completed the wiring. So far looks like pin 3 will be my trigger wire for high beams. Headlight Pin 6 will be DRL trigger. Also think I’ll forego using any factory upfitter switches and be wiring direct to battery with a 40amp fuse.
I’ll report back when I complete the permanent wiring.
2.5hr install so far. Still have to final wire everything. Probably be asking for wiring help after some searching.
Wanting smber DRL on with factory headlight DRL’s, Aux switch 6 or 1 turns on light bar and light bar lights up with high beams only and only if aux switches on.
Waiting on...
