Question:

Please recommend what I need to install a 7 blade pin round truck connecter onto a 1993 1500 Silverado 4WD with no previous or factory provisions for a connecter. A factory color coded wiring diagram of rear lights would be very helpful. Thank You Kindly.

To add a 7-way connector to your 1993 Chevy truck you will need to add a couple of wiring harnesses. The first one is the Curt T-Connector Vehicle Wiring Harness item # C55315. This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the rear bumper, along the driver's-side frame rail.

The second harness you will need is the Universal Installation Kit for Trailer Brake Controller item # ETBC7. The kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your vehicle with an included bracket. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it.

You will then connect the blue wire to the blue wire on the brake controller, connect the black wire to the positive post on the vehicle's battery, the white wire to ground, and the yellow wire to vehicle's reverse circuit if applicable. This will provide you with the ability to control your trailer's brakes and also provide you with a 12v power wire for you trailer's accessory lights.

I don't have any factory color coded wiring diagrams for a 1993 Chevy truck but I have linked a couple of installation videos below that will help you with the process. You won't have to splice into your tail lights with either of these parts.
