I need a Crew Cab wiring harness

[KrewKabKid]

I've spoke to Painless, Brothers Trucks, and American wiring none of them have a new complete harness for my 86 K3500 Crew Cab. All I can find is a standard cab long bed harness, who knows where I can get one? Thanks

? All you need is extra dome harness length and extra tail light harness length.. maybe fuel sender wire? Unless hacked up real bad the factory harnesses are just fine.

^This. Would be very simple to modify one of the RCLB harnesses

Yes my harness is all hacked up. I just figured if these companies made a factory style standard cab harness there would be one for a CC but now its clear they don't. I'll just have to extend the wires on a LWB standard cab new harness like you mentioned. Thanks

Either of the harnesses listed will cover a crew cab. the only difference is the rear harness but there is usually a little bit of extra that will get you close enough to the back of the truck to make a connection harness. AA makes a tail light harness to continue from here. The rear wires are long enough to go to the back of a longbed and then to the passenger side from the drivers side frame which will make them long enough to go to the end of the frame on the driver's side on a crew/long and convert from the plug setup.

If you have dual tanks and a TH400 go with the painless and buy the extra parts. I would still rock the AA harness even with those but if it's your first harness you may not want to.
