4-Way to 7-Way Extension Recommendation for towing a Trailer with a Truck
Updated 11/17/2025 | Published 12/10/2024
Question:
The 4 flat connector on my trailer isn't quite long enough to reach my truck connector. It also doesn't match because my truck has a 7 round connector. Do you have some type of extension or something like that?

The best part about this is the coiled wire because it gives you the length of wire you need but is also able to keep the wiring up off the ground.
