I've successfully installed the break controller follow the jeep instructions.
the only difference is that you have to take the blue cable that is coiled up in the motor compartment and send back to the driver's compartment And the break wire is withe withe a green stripe (you have to tested to be sure).
To pass the cables i used a flat screw driver to punch the whole trough the rubber barrier (is hard you will here two pops).
I didn't used an utility knife because the space is too tight and I was afraid of cutting some wires.
After that I used a dry-cleaner hanger i passed it through the whole and then attached the cables to the end, tape them and pulled them inside.
the rest of the installation is like the Jeep except for the break cable (the white with the greens stripe one)
