That's for the trailer stop light circuit. It won't help the D4 recognise that the trailer is connected.

Yes correct as I've already have the trailer detection sorted.

Aah! So you have. Neat solution.

Here's how I did mine......

Installed two Resistors on the Indicator wires.....fixed to a small piece of RHS Aluminium cause they get hot under load....(not sure if that's the ACTUAL link to the ones I bought, but very similar)

7 Pin fits into the 12 pin just as well as the 12pin....

Here's the D4 12s/12n set up for your wiring....in case anyone needs it on this thread.

I installed the Redarc brake controller on my previous Mitsi Challenger, but had the Tow Pro Elite installed by the dealer when I picked it up.....I wasn't that keen on drilling holes in the dash of my brand new baby haha :)

Righto, got all the cables run down to the back of the car and was going swimmingly until I read the circuit diagram as provided in the Sticky document and looked at the trailer wiring. They are different. Instructions says there should be a black and a brown wire. I have a brown and yellow with brown trace, no black wire. Is there a different circuit diagram for an MY16?Any ideas or better still is there a sparky in Perth that has done a Towpro install I can take it to?

This is from Scott's post #506 in the brake controller sticky:-

D4 Electric Trailer Brake Wiring

The splice that I think you want is usually hidden behind a loom label in that cubby area.

Pete

I have a MY16, in the passenger side compartment of the boot area the splice is covered with a white label that needs to be removed. Once removed you’ll see a brown wire running into the black splice then both black and brown wires coming out the other endhttps://www.aulro.com/mobile-gallery...9ce726aa37.jpghttps://www.aulro.com/mobile-gallery...afb8d6a2a8.jpg

Ah ok. Haven't done that bit.
