Parts Needed to Install 7-Way and Brake Controller in 1981 Chevy Truck  


Need recommendation for new trailer wiring in a 1981 Chevrolet C20 crew cab. Need: wiring from cab to rear bumper, a 7-pin receptacle for travel trailer and another one for utility trailer so I can use either one without an adapter, etc., trailer brake control looking at the Primus IQ and any other wiring ETBC7? that I need to supplement my factory lighting harness. Thank you.

For 7-way wiring you could run from the cab of your truck back to the rear of it we have the jacketed 7-way wiring part # DW04914-1. We don't normally offer wiring for this portion of a vehicle but this would work if you have the 7-way wires present near the cab.

Normally in this situation we recommend installing a 4-way like the # C59496 which wires to taillight circuits and then converting to a 7-way with the # ETBC7 like you referenced so that you can install a brake controller like the Tekonsha Primus IQ part # TK90160.
