I need a 5 wire female plug to 7 way plug to truck. Purchased Rice trailer in 2015 and need the wire harness from my truck to trailer about 6 feet back. I can send a picture of what i have. It also had a red, white and blue wire sealed into the unit for battery hook up auxiliary. Thanks TOM

Hey Tom! For a 7-way to 5-way adapter you can use the Mighty Cord 7-Way RV Style to 5-Way Flat Trailer Connector Adapter # A10-7275VP. If you need an extended adapter to reach you could use the Curt # C84HR instead which can stretch up to 96" when fully extended.

If you're trying to replace the trailer wiring, you could use the TowSmart 7-Blade Trailer Connector # TS74RR you were looking at and replace the 5-way so there is no need for an additional adapter. This is 72" long and you can just ignore the colors and match the functions to wire it in.

If you're looking for something else let me know in the comments below. Feel free to email me your pictures as well if you still think it is necessary.

What do you typically haul with your trailer?
