7-Way to 5-Way Flat Trailer Wiring Adapter Recommendation
Updated 01/07/2016 | Published 01/06/2016 >
Question:
Hello - do you have an adapter to fit my 2014 Silverado 1500 to be able to connect my 7 wire round truck plug to the 5 wire flat plug on my Range boat trailer? The 5th wire is for the trailer brakes. Also, the trailer has LED lights. Thanks!

Expert Reply:
The adapter you would need is the part # A75TB. This is a 7-way round connector to 5-way flat adapter that would work great on your 2014 Chevy Silverado 1500.
The fifth pin on your boat trailer SHOULD be for a reverse lockout solenoid on your boat trailer that most likely has surge brakes. 99% of boat trailers with a 5-way flat are configured like this.
