Universal 4-Way Wiring Harness that Can Fit Tiffin Built on Sprinter Chassis

Question

Question:

The website says this is not confirmed to work on my 2019 Sprinter, nor is it for vehicles with LED lights. https://www.etrailer.com/p-C59496.html Im trying to determine, however, if those warnings apply to my situation. I have a class C RV built on a 3500 Sprinter Chassis. The upfitter, Tiffin, uses LED lights in the rear of the coach driven by the Sprinter wiring. They also have load resistors to make the LEDs work and avoid the lamp out error. I am considering this system to avoid the Sprinter trailer control module which has given me no end of difficulty.

The Curt trailer wiring harness part # C59496 is a universal style 4-way kit that can be used on vehicles like your 2019 Mercedes Sprinter 3500. Since the Sprinter has standard wiring but the RV has LED lights it could work as long as you connect to wiring that for sure was designed to power incandescent lights.
