Garrycol, where did you see the EBRH unit for $164? It's listed at $280.39 on Redarc's own web site!

Sniegy,

I'm going to fit a Traxide DB kit on my MY08 D3 next weekend, and thought I'd at least run the wiring for the EBRH unit at the same time as I'll have all the same panels off. I don't have much of an idea about auto electrics: could you advise me on the wiring (length, type) I'd need to purchase to "make my own loom" to do this, please?

Thanks very much to you both.

Cheers, Gaviatrix

Gaviatrix, check out Ebay. $160 for a basic kit or $200 with extra wiring...

The trailer has override disc brakes but am thinking of fitting electric over hydraulic. Will the Red Arc unit work on hydraulic brakes? I asked them some time back and they replied that it "is not certified for hydraulic".

Hi Andrew,
The Electric brakes will not run Hyrdaulic brakes & will need to be changed to Electric for correct operation.

Hi Gaviatrix,
The loom will need to consist of 4 wires, red/blue/black/white approx 5.5 Mtrs long. They will run from the position you mount the Electric trailer brake unit to the L/H/R 1/4 panel. The wiring should be minimum 4mm squared for best results. Refer to the D3 Electric trailer brake write up in this forum.
Any questions please ask.
Cheers

The P3 supports this option.

Thanks Graeme

Can I ask the question again:

Are there instructions on here (or anywhere) for installing the Redarc EBRH unit into a D3?

Thanks.

Sneigy, thanks very much indeed. I'll buy the cable and run it when I do the dual battery instal next Saturday. I bought a Redarc kit on eBay last week so I'll be right now.

Really appreciate your help, thanks again.
