Most Popular Wiring Adapter for 2013 GMC Sierra

Simple plug and play in my 2006 GMC Sierra 1500 to my P2 brake controller. Took less than 5 minutes to install. Thanks Etrailer for another excellent product!

Haven't pulled with it yet but everything in the order was correct. Install was easy and shipping was fast.

Makes installation a snap to wire up. Also makes it convenient you can use between other vehicles pretty much makes it a plug and play. I have 3 of them in our vehicles and there all the same set up. So if one did go down i can take one and swap it out with another one. Just need another mounting bracket and you can have 1 controller for 2 vehicles.

Tekonsha wiring adapter GM-3025-P onnected the brake controller to the GMC Sierra built in wiring and fit/functioned perfectly. eTrailer made it easy to find the part and assure that it was a "plug & play" component.

As always this website rocks! Installation was easy enough thanks to the video.

Great product. It plugged into the trailer brake controller I order just like I hoped it would. The wires were about 14 gauge, nice and heavy. (Better quality than the GM factory wiring that was in my truck.) Each wire was labeled, for example: brake, ground, etc. I am glad that I ordered it. Why? Because if I hadn't, the factory installed wiring in my truck, and the wiring on my brake controller, would not have been long enough. So, buying this product was money well spent!

Adapter was necessary for it to work with the trailer brake. It was a plug and play unit. No cutting of wires.

WORKS AS DISCRIBED. PLUG AND PLAY

The harness worked great on my 2009 GMC Sierra 2500HD. The guys at etrailer helped me find the right harness to connect the Curt brake controller I already owned. The customer service is great. I really appreciate how helpful they are.

The easiest way to wire your Curt brake control. It's low priced too. A no brainer. I purchasedt it as a package with the Curt brake control.

This product made hooking up a trailer brake unit very simple. I would recommend this to anyone looking to set up a trailer brake unit.

Great! Quick delivery!

perfect product. excactly what I was looking for. Very well made

The wiring harness for the Prodigy P3 brake controller made installation in my GMC Sierra a breeze. Plugged right in and ready to go.
