Thread: LED trailer and resistors

Just remember that he was trying to help, even if he did stuff it all up. Burn him and the good will goes with it.

Here are the wiring diagrams. If the vehicle is 7pin, then consider 7 pin for the trailer. Most these days are 7pin flat.

Load resister - These allow more current to flow to simulate the power drain of globes - this is for vehicles with circuits that sense trailers by the power drain from the lights.

He was on the clock so was getting paid for it. Anyhow...
The LED lights only have 4 wires not 5 like the plug. So what colour would the negative to splice on that set up? I'm not prepared to spend to much more time on it and I'm thinking just go to the auto elec and he can do it good and proper

Hi,
I don't know what your mate found at the rear of your vehicle, but if you only have four wires on the LED lights, something is wrong.
You need:
Tail
Stop
Left
Right
and a common, or earth.

Ideally you should also be installing:
Reverse, as well.

So you should have a seven pin plug, round or flat to match the vehicle.
A seven core cable, but five would do.
(the seventh wire (blue), for electric brakes is probably not required)
Do not rely on the towball for the earth connection.

Follow the code as given to match the plug/socket combo.

Look at the LED setup again to find the fifth wire.
