Need help with the brake and rear turn signal
 

Hello, I need help to be able to separate the signal of the brake from the turn signal, for brake I´ll take the signal from the 3rd brake light and put the turn to the backing light.
I have tried disconnecting the brake signal that comes from the pedal, but this block the transmission, another trait I have disconnected the cables that leave the BCM where the brake and rear turn signal goes together and connected the rear turn signal to the front turn signal but it is flashing very fast, don´t know what to do.
Thanks for helping

For what purpose, towing a trailer?? There are usually special electronic boxes made for this purpose that you splice into the harness. Hoppy is a brand that comes to mind as i have one in my sports car for the trailer harness.

I just checked the Hopkins website and it indicates nothing special needed for a tow harness. Has the color code for the wiring there in the instructions file.

Does this help you in anyway?

The purpose i that here in Sweden the turn must be separated from the brake and the color is not the red for the turn

Solved the problem
 

with two resistors (6,8 ohm) to the turn/brake´s circuit that i cuted and two relays to the new turn circuit that uses the same cables to the old one turn/brake´s signal on tail, and the tail brakes work now with the center brake light circuit, the dealer doesn´t know if the reprogram the BCM was possible, so now i have separated the turn signal and the brake light and works perfectly.
