Trailer Wiring Harness for 1999 GMC Sierra 1500
Updated 06/16/2017 | Published 06/15/2017
Question:
I have a 99 GMC Sierra 1500 pick up that has a connector with 4 plugs plugged into it under the rear bumper. Which plug and play harness do I need to purchase? I need a 4 way. Here's a photo of the connector under my bumper. Thank you

Expert Reply:
Since you don't already have a factory connector on your 1999 GMC Sierra a 4-way trailer connector will need to be hardwired in.
I suggest using the # C59496. It includes all the wiring and connectors you'll need. It also includes a circuit tester so you can find the correct wires to connect the harness to. The wiring on your truck will need to be probed to find the correct functions to connect into.
