Review on 🚚 Custom 4-Pin Trailer Wiring Harness for Ram ProMaster 1500, 2500, 3500 by CURT 56209 by Randy Butler

Revainrating 3 out of 5

quick installation but lacks functionality

Pros: - Fairly clear instructions with color photos - Installs in 45 minutes - Includes everything down to zip ties. Cons: I've tried various sequences to turn off the Promaster lights, but I could never get the U-Haul 4x8 trailer taillights to turn off unless I unplugged the wiring harness. If I hadn't noticed, I probably would have woken up with a dead battery in the middle of the Utah desert.

Pros
  • Automotive
Cons
  • Only available in white
