Question:

My truck has a 4 pin flat trailer connector. My trailer has a 7 pin round connector. Is there an adapter available 4 pin Flat to 7 pin round? Thanks

For an adapter you can use the Custer Trailer Connector Adapter - 4-Way Flat to 7-Way Round # KIT-7P-4. The 4-way on the adapter will connect to the 4-way on your vehicle and you can cap off the other functions you don't need. Keep in mine, you will need to attach the ground wire with a screw so you may want to consider a permanent installation.
