Typical Trailer Light Wiring Diagram / Schematic  

The warmer weather is here. Many of us are getting out our boats, jet skis, and other toys on trailers. Do your trailer lights work properly? Do you have to add a trailer light socket to your vehicle? Are your lights wired wrong now? Here's a few typical trailer light wiring schematics. We all know how confusing adding a trailer light socket to your truck can be.
I suggest buying one of the T connectors. Made by companies such as Draw-Tite. For 73 - 84 Chevy/GMC C and K models, the Draw-Tite part number for a T, for 4 pin trailers, is #18311. I paid $15.95 locally for mine. Six pin is #18320 (metal), and 7 pin is #18321(plastic), 7 pin #18322 (metal). These numbers are for all 73 - 84 C and K models. My father's Grand Cherokee was over $70.00!!
Without a T connector, you'd use quick splice connectors. Over time, these allow the wires to corrode. When they tap into the wire, they slice the insulation. Salt and moisture get in, and corrode the wires. Dim tail lights are a usual result.
