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’m looking for a flat four wire plug/assembly with built in resistors for the led lights on my trailer.Do you have them or know where to get them?

We do not have a trailer wiring harness for the trailer side that has resistors built in for LED lights. We have resistors that you can wire in separately that work great. They are # P230004A-2 and you will have to wire them into the right and left tail light signals.

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?

The resistors shouldn't interfere with the T-One Harness at all. If anything it might better ensure proper operation of the trailer lights.

You may not even need load resistors to switch to LED lights. The best thing to do is to try the lights without load resistors first. No need to purchase something you may not need until you know need it. Load resistors such as #DI34ZR dissipate heat…
