Question:

Im installing a P3 controller on my 2013 chevy silverado 2500HD. Truck came factory with a complete hitch package and factory controller. No where can I find an answer to the following questions. 1 Do I have to disconnect the plug on the factory installed brake controller or just let it plugged in 2 the P3 controller has ion for electric or hydraulic braking. Im assuming that I have to Hydraulic for using my electric over hydraulic brakes, correct? 3 Do I have to install the 20 amp o/l protection for my trucks + hot wire to the controller or not? The video you provide for a 2013 chevy truck doesnt even talk about this but the P3 drawing shows needing one.

Hello Wendy, thanks for reaching out.

To answer your first question, take a look at the article I linked below. It will go over exactly how to bypass the factory controller in your 2013 Chevy Silverado 2500HD.

For your second question, yes, you will need to switch the P3 controller to hydraulic mode for it to work correctly with your electric over hydraulic braking system.

For the 3rd question there should already be a fuse location for the brake controller so an in-line fuse would not be needed.

Fell free to reach out if there is anything else I can help with.

Thanks for reply even though I had to figure it out on my own 2 days ago then get a reply after the fact. It would be so much more helpful to customers if in fact that when someone purchases a controller per a specific vehicle search that any available instructions per that vehicle is provided. Only instruction was per a new install and nothing per replacement of a factory controller. This would have prevented a lot of frustration on the customers behalf. Luckily I chose the correct size wire to run, so at least now I know I don't have to mess with having to replace what I already did and that my install is correct to what I had to figure out on my own. Hope things improve for the customers behalf.
