Question:

I have an 04 GMC Yukon XL Denali and am looking for a trailer brake controller for it. The trailer Ill be pulling has 2 axles. Im not exactly sure which controller I need to buy. Ive located the panel and which port I need to plug into, just need the equipment now. Thank you!

For your 2004 GMC Yukon XL Denali I recommend using the Tekonsha Primus IQ # TK90160 with the Adapter Wiring # 3015-P that plugs into the port you found. The only other thing you'll need is the Trailer Connector # 30955 and that's only if your Yukon XL doesn't already have a trailer connector.

I like the Primus IQ because it is a cost-effective yet reliable proportional brake controller. It will activate your trailer brakes in tandem with the braking on your GMC and comes with a limited lifetime warranty that is backed up by a multitude of excellent reviews on our site.

It sounds like you're ready to hit the road with your trailer as you've done most of the groundwork on your end. Happy towing!
