2004 Chevy Silverado Trailer Brake Controller Wiring. Equip cars trucks SUVs with 2004 Chevrolet Silverado 1500 Trailer Brake Control Harness from AutoZone. To begin with well go ahead and locate and area where we want to mount the brake controller.
I recommend the Tekonsha Prodigy P2 90885 and Wiring Adapter 3015-P. The functions of those wires should be as follows. Designed to meet the highest quality standards it is second to none in durability and performance.
Light green - reverse lights dark green - right turnbrake.
Luckily your first-generation Silverado already has a the necessary wires to make a hitch harness so all you need to do is install the plug. Step 1 Install the brake control in the cab according to the instructions delivered with the unit. The Hopkins Plug-in Simple Brake Wiring Adapter HM47795 should have the red wire run to the pin right next to the blue wire closest to the clip side of the connector. The P2 is a great unit for the price and is very easy to install and set up.
