The Tail Light Isolating Diode System with Wiring Harness # 38955 you were looking at is for towed vehicles so I misinterpreted your question and recommended the additional diodes. If you were just wanting to wire your trailer for separate lighting then you'll just need a converter # C56196 and you'll splice it in after the 7-way/junction box on the trailer.

On the 7-Way wiring, locate the wire for the left turn and brake and attach it to the yellow wire on the converter input side. Connect the wire from right turn and stop to the green wire input side. Ground the white wire to the trailer frame.

On the output side that will go to the trailer lights, you will have the yellow wire, which will now be left turn only, the green wire for right turn only, and a red wire for brake lights only. The running light wires will remain separate.

Since your brake wire is separate from the turn signal you will need a converter. The Curt 2 to 3 Wire Tail Light Converter #C56196 will separate the turn signal and brake signal. Wire this into your 4-way on the trailer side and connect your blue…

Yes, you can use wood screws to secure the e-tracks to the plywood walls in your trailer. However, as you mentioned the weight capacity would be less than if you were to attach them to metal beams. The tracks themselves can handle up to 2,000 lbs but…

While we don't have anything specifically designed for that you could maybe use the Spring Latch w/ Cover and Holdback #F779-204U234 installed on the ramp which you'd then be able to push the pins up to lock the ramp up from the inside to the…

Since trailer wiring doesn't always abide by the typical wiring color standards I won't be able to tell you exactly where everything needs to go but I can help you figure it all out. Sounds like you have a 7-way on your trailer and the colors…

Normally, the green wire on the right side carries right turn signal and brake light functions and the brown wire carries running light functions. On the left side, the yellow wire carries left turn and brake lights and the brown wire again carries…

Answer 9

The yellow/brown and green/brown wires are the running light circuit on the trailer. The new 4-way that has a single brown wire can still be used but you will need to run both wires of the trailer to single brown wire on the 4-way. This is a very…
