Question

Question:

My 2003 Chevy Silverado 1500, does not have all the necessary wires from the cab to the fuse box its missing the blue and red wires. What is the connector type used in the 3015-P?. Once Ive added/run the wires I would like to terminate them with the right type of pin so I can add it to the junction box under the dash where the 3015-P connects

It's actually easier to activate the brake controller wiring of your 2003 Chevy Silverado so that you can use the part # 3015-P that you referenced.
