It sounds like you need to add a 7-Way RV style trailer connector to your 1997 Chevy pickup. Since you already have a connector, you will just need to add a 4 and 7 Way Installation Kit, # ETBC7. Though I am not certain if you have a 5-Way flat connector or a 4-Way flat connector. If you have a 4-Way, it will plug into the back of the ETBC7. If you have a 5-Way, I recommend first installing a 4-Way using part # 118315, and plugging it into the back of the ETBC7.

With the 4-Way plugged into the ETBC7, there are just 4 wires left that need to be hardwired to the vehicle. The white wire grounds to the truck frame. The purple wire gets connected to the reverse light circuit behind a tail light (if needed). The black wire connects to the positive battery terminal via a 40 amp circuit breaker (included). And the blue wire attaches to the blue wire on the back of a brake controller.

The kit comes with everything needed to add a function 7-Way trailer connector and provides the wiring and circuit breakers needed for brake controller installation. A brake controller will be needed to activate the electric trailer brakes on the trailer. I recommend the Tekonsha Prodigy P2, # 90885. It is one of our most popular controllers because it is easy to set up and easy to use.

I have included links to FAQ articles and a video explaining the installation of an ETBC7 kit, the 4-Way wiring harness installation instructions, and a trailer and trailer connector wiring diagram for reference.
