Installing Prodigy P3 Brake Controller in 2016 Silverado 2500HD with OEM Controller


Bought 3016 harness to install. ? Is does the oem controller need to be unplugged. And is it correct that when using the 3016 harness no other wiring is required. Thanks


Expert Reply:

You can install a Prodigy P3 Trailer Brake Controller # 90195 in your 2016 Silverado 2500 with OEM controller but you will not use wiring adapter part # 3016. The necessary wiring for an aftermarket controller is present under the dash.

Four or five blunt-cut wires are under the left side of the instrument panel. These wires are located above your left shin as you are seated in the driver's seat. The wires can be identified by a white label and the color of the wires. The wire colors are (1) Red/Black wire, (1) White wire, (1) Light Blue/White wire and (1) Dark Blue wire, and possibly (1) Orange wire. Please see the linked photo.

The linked article addresses this specific installation and gives you detailed instructions for wiring your P3.
