91 Suburban/Crew Cab Relay Harness

[monte0185]

Hey everyone. Im swapping my 86 Dually over to a 91 Burb front core support and need some info on the headlight wiring. I have my old wiring and I also have a relay harness for the 86 headlight setup but since the headlights have different connectors I was wondering what everyone was doing to wire theirs up. Are you using a different relay harness if so what part number or are you just swapping the plugs on your old harness? Ive read some people just swap out the whole harness from the firewall and that would be great if i had the 91 harness.

I have a brand new set of headlight pigtails so Making my own relay harness is not out of the question. Im not sure how I can make the low beam and high beam both light up on the brights i guess is where im having the most problems since the older low beam lights had 3 connectors and not 2.

So everyones opinions and help would be great.
Thanks in advance!!
