Have you looked under the vehicle? I'd be surprised if the wiring harness wasn't already there and taped up under the vehicle.
Barring that, most business that sell and install trailer hitches will also install trailer wiring harnesses.
If you're a DIY, go to the local auto parts store and ask. They probably have the wiring harness you need all setup to plug into the manufacturer's wiring harness.
Depending on whether you have the towing package or not, about 7500. But really, they can pull just about anything you want to pull. I do not know how much they are rated for if your burban doesn't have the towing package. Probably 5000 or less.
3500lbs with factory towing package.
Plug in the trailer harness into the 7 pin hookup next to the receive hitch if you have a stock towing package.
A Chevrolet Suburban 1500 will have about 4000 LBs (about 2200 KG) towing capacity.
Towing capacity of a 4x4 double cab V6 model is 6500# with the towing package. Without the towing package it is 3500.
Per GM this vehicle tow rate is 9,500 lbs.
Towing capacity: 3,674kg (8,100lbs)
The listed 1996 GMC suburban K 1500 towing capacity is 7500 pounds. Towing more than 7500 pounds will void the warranty.
2,000 lbs. unless you have the optional towing package. With the optional towing package, it's 3,800 lbs.
It has a trailer brake controller, upgraded bumper and towing mirrors. Also includes the items listed on the tow package.
