Expert Reply:
LED type trailer lights use very little power, about one-tenth the amount required by standard incandescent light bulbs. This can cause some wiring systems to not "see" the trailer lights because their current draw is so low. In some cases a wiring harness may not function correctly if used with LED lights unless a load resistor is installed at each LED light unit.
We offer 2-piece ceramic load resistor kit # DI34ZR which will allow your harness to operate properly with LED trailer lights. You'll install one resistor at each LED light.

I have these setup on my 14 Sienna. Will the load resistors interfere with a trailer wiring harness T-connector 4 pole that Im about to buy from here?
