KY WTB 69-71 suburban under dash wiring with rear AC and gauges.

[72chevynut]

Hello, I'm looking for a good complete under dash wiring harness for a 69-71 suburban with rear AC and full gauge cluster. My 71 suburban has the idiot lights and want to convert to full gauges. It will need to come out of a suburban due to rear taillight/AC wiring pigtail plug that is located near headlight switch pigtail plug. Attached is picture of the rear taillight/AC plug on mine for reference. Appreciate any help with this and willing to pay reasonable price for parts and shipping. Thanks

I recently parted out a 72 suburban with rear a/c and it had a regular truck wiring harness, I guess they changed the harness in 72.

I'm not sure exactly when they changed. I figured any suburban with the rear AC only setup, the 72's had both front and rear AC. My suburban has just heater controls in front dash with the AC controls in roof console. I know I was planning on it being a quick change out until I seen that extra plug near the light switch plug. I have several pickup/blazer underdash harnesses I could have used. On my suburban, all the rear wiring runs through the body starting in a hole on left kick panel instead of below body along frame like trucks. It kinda messes with ya if your mainly use to trucks and blazers. Lol, same way on firewall behind engine, no plug with wires.

I have one out of a 72 GMC I cut up 30+ years ago. I'll have to dig it out and see if it's what you're looking for. Ken

I appreciate you checking Ken. Seems like GM made some changes in 72 on the suburban AC stuff but we might get lucky. I really would like to get mine switched over to factory full gauges while I still have it apart.

Sorry Michael, Just looked and it's a bunch of random pieces of looms. Nothing like the plug in your photo. Ken

Thanks again Ken for checking, I really appreciate it.

Anyone else have anything? Here is a pic my suburban, I pulled it out of shop today to wash off the dust. Hoping to get it back together soon.

Why not repin you existing harness for full gauges ? It's really easy to do.

Thank you 72MARIO for the ideal and link to information! I will have to study on this a little bit more to make sure I get it right if I go this route. I also found some other information on doing this type of change over and it gets a little confusing to me with the extra wires needed out in the engine compartment. I would like for it to look and work like factory and I can wait a little longer to see if someone comes up with the correct harness. Thank you again for the response.

Still looking for correct harness. Thanks
