Does anyone have any suggestions as to the best company or location to get a new wiring harness for a 1981 pontiac Bonneville? Thanks!
An entire harness? that's a monumental task, sir. GM if available(pucker up!) or wreckers, I'd bet the farm nobody is reproducing these.
Try American auto wire for an exact one or painless wiring has a good universal kit just use the one in my 59 Chevy
We used lots of EZ Wire kits. It's a universal well marked wiring harness out of Bunnell, Fl just north of Daytona. Much cheaper cost and had no problems with many installations on street rods and stock antiques. Not really sure if they are still in business but try 'home of EZ Wire' in search. We also bought gauges from them. They started out as two brothers taking over dad's boat gauge business.
1980s Bonnevilles are not popular to restore. No one sells a brand new replacement harness. Your only options are rewiring using a generic kit or repair the one you have or find a good replacement from a parts car.
