Factory Brake Wiring Harness Location on 2012 Chevy Silverado

Question

Question:

I have a 2012 Chevy Silverado LTZ 4x4. I have purchased the Technosho Prodigy P2 brake controller. I have looked and looked under the dash, to the left of the Brake pedal and can NOT find the wires suggested to complete the brake controller install. Can you help me with where these wires could be. I tow a trailer and use the tow lights and the 7way light plug works great, I just can’t find the wires I need.

When installing the Tekonsha Prodigy P2 Trailer Brake Controller # 90885, we need go back under the dash to find the factory wiring on your truck. Now it's located behind the dash underneath the steering wheel just a little towards the left and a little bit left of the brake pedal. It's pretty far up in there so it'll take a while to find. After you find it, take the wires and gently pull them down. I have a video attached that does a great job of locating the wires on your vehicle.

I do have a solution for your 2024 Kia Telluride that has the LED taillights that does allow it to have both a 4-way and 7-way plus install a brake controller but it is not with the #TK74CR which does not work for you based on the LED taillights.…

Answer 7

You are correct, you should only be getting output when the brake is applied, or the override switch is activated. It sounds like the controller might be bad, but to make sure, you should probably bench test it before tossing it. Use a circuit…

Hi Bruce, To lift your trailer we'll first need to check of the suspension and see if you have torsion axles or a leaf spring suspension. If you have torsion axles then I'll need to see the axle tag in order to determine what you have so I…

Hey John, so the correct amount of spring bar tension will be based on the trailer's tongue weight and how it affects the suspension of your Nissan Frontier. Every WD system is a little different but what it comes down to typically is measuring…

Answer 10

The attachment bolts for a 5-bolt brake assembly like the part #AKEBRK-6R should be torqued to 30-50 foot/lbs. If you don't have a torque wrench handy, if you tighten the bolts until the lock washers flatten out, you'll be pretty darn close…

Normally a bumper is rated at about 3500 lbs towing capacity. It is usually stamped somewhere on the bumper or possibly on a sticker. A frame mounted hitch is going to have more capacity for towing due to how it is installed. Also, most trailers will…
