Question:

Hello, I have a 32foot travel trailer that I recently put a Rola storage tote on the rear hitch. The Rola has a 4 way plug to run the brake lights and turn signals that it came with. I thought about tapping into my trailers rear lights, but since the storage tote is removable Id prefer to just wire it in a way that I can easily remove it. I thought it would be easiest to just connect a 4 pin plug to my trucks trailer receptacle. The trailer connects to the truck with the round 7 pin, leaving the 4 pin available. Of course, that plug is now 35foot feet behind my trucks trailer connector. Im looking for a 35foot extension for that 4 way plug. Any product suggestions? How heavy gauge wire should I use, considering its only running two incandescent tail lights? Thanks,

For a 40 foot long section of 4-way wiring that includes the connector we have the part # A40W42B. The for a 4-way to wire to the other end of the harness we have the part # HM48030 which would complete your 4-way extension.
