Question:

Im planning on towing a car trailer. I would like the option of having both 4 pin, and 7 blade connectors. Can you suggest a wiring kit for me?

I do have an option for you but semi tractors use separate stop and turn signal circuits and they will need to be combined to tow a recreational trailer. Therefore, you will first need a converter like the Hopkins Tail Light Converter part # HM48847. Then you can wire up a trailer connector like the 7-Pole and 4-Pole Trailer Connector Sockets part # HM40975-11998 which comes with both a 4 and 7-way as well as a mounting bracket.
