Hi There. Looking to bypass my factory brake controller and install a Tekonsha Prodigy P3 Proportional Brake Controller Part 90195. However, Im not able to find this on your website? Also, I want to be able to plug it into my truck 2015 Chev Silverado 2500 HD 6.6d.. Do I need an adapter to make that easy?

Hey Rene, welcome back! Unfortunately, the Tekonsha Prodigy P3 brake controller is currently unavailable. Tekonshas parent company went belly-up and they stopped producing and shipping product. They were bought out recently, so we are hoping they will resume operations at some point, but there is currently no ETA for when that would be. So, right now we can't provide the P3 controller or any compatible pigtails for it.

That said, we can still provide a plug-and-play brake controller for your 2015 Chevy 2500, it just wouldn't be the P3. Here is what I recommend:

- Redarc Tow-Pro Liberty Brake Controller w/ Custom Harness - Dash Knob - Up to 2 Axles - Proportional # RED26CR

This controller installs hidden behind the dash, and all you see is the small LED control knob. It comes with a custom pigtail you can use to plug in directly to the factory brake controller port on your Chevy. I really like the Redarc controllers. They are dependable, easy to use and they don't take up hardly any room on the dash.

What kind of trailer will you be hauling?

Hi Jesse, I'm towing a 12K lb 5th Wheel - Dual Axles. Would your suggestion be a good solution for me? Thanks Rene G

@ReneG Yes, the Redarc is a great solution for that! It is designed to work on trailers with one or two braking axles. I think you will be very happy with it. The P3 is a great controller too but it might be quite a while until you could get one.

Can you tell me a little bit how this works? Does this bypass my OEM controller and supply its own power to the back of the truck using the truck modules? Thank you, Rene G

@Rene Yes, you can install a Redarc aftermarket brake controller on your 2015 Chevy Silverado 2500HD and bypass the factory integrated brake controller. You don't need to physically remove the factory controller or disconnect its module. The Redarc will connect to the truck's brake controller wiring under the dash, but you'll also need to run a separate brake output wire back to the 7-way trailer connector. This bypasses the factory brake controller's output so the Redarc controls your trailer brakes instead. GM actually has a service bulletin, PIT5282B, covering this exact conversion.

@JesseM Ok. Thanks. Seems like the right way for me to go. Just to confirm, assuming I have my year and truck entered in your web page, the correct connector will come with the kit. Correct? Thanks for your help here Jesse! Rene G

@Rene Awesome glad to help! Yes, that's right. The # RED26CR I mentioned comes with the controller and the custom connector for your Chevy.

Rene, I just installed the Redarc Tow-Pro Liberty in my 2017 Silverado 1500 and it works great. Really like that the controller button is small and unobtrusive on my dash. There is a perfect hollow behind the small flat panel above the headlight switch. The install was pretty easy, plugged it right into the factory port behind the cover panel by your left foot and drilled holes to strap it to the cover. You can mount the module in any orientation as long as it is solid. It can't be swinging around or it won't function correctly. I was going to post my pictures of my install but this app won't let me attach pics.
