Recommended Wiring Harness With 4-Way to Rewire Flatbed Trailer
Question:
I need to rewire my 18 foot flat bed trailer. 4 pin flat connector, no brakes, front side markers, what would you recommend?

Expert Reply:
The 35 Ft 4-Way Trailer Wiring Harness # A35W42B you were looking at is what I recommend. This will give you plenty of extra wire to run to your side marker lights. I always like to have extra just in case since running out of wire in the middle of a job is the worst. Any extra you don't need can be cut off when you wrap things up. This also runs a little cheaper right now than a 25' harness like # A25W2GWB so it makes sense to get the longer one.
