Brake Controller and 7-way Trailer Connector Installation on 2019 Chevy Suburban

Question

Question:

I am in the market for a used suburban, likely 2019 to replace an older suburban that has a hitch and standard 7 plug. I do not have a brake controller for electric brakes. The replacement suburban i want to make sure I can install a brake controller as I do also have a landscape trailer I tow with an older chevy truck. My question is, as I look at used suburbans, quite a few on-line, do I need to make sure the vehicle has a tow package or trailer package? I seem to read different information that is unclear. Thanks in advance.

Just about every full sized domestic SUV and truck will be equipped with a factory hitch and 7-way. If it lacks the factory 7-way, there will be a round US CAR connector under the rear bumper or above the spare tire that would plug into a connector like # HM40975.

The Suburban will be equipped with the connection under the dash for the brake controller located in the junction box behind the emergency brake pedal as shown in the install video I've linked for you.

If you don't already have a brake controller, I'd recommend the Tekonsha Primus, part # TK90160. The Primus is an easy to use, inexpensive and very effective brake controller. You'll also need the # 3016 wiring harness.

The wiring harness that you need is part #3016. One end plugs into the P3 brake controller, part #90195, and the other end plugs into the connector under the dash of your 2019 Chevy Suburban. Since you have the tow package you'll have that…

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…
