Thread: Towing Upgrades

Diodes are necessary, so is cutting the wiring behind the taillight.

It's easier to install a 12 pin plug on your disco, then you can plug in 7 pin flat and 12 pin flat.. Osborne Park autospark sell good stainless brackets to mount these.. most trailers are 7 pin flat. The 7 pin round are the small type. I used to carry adapter's. But now I only have 1.

Hi Rod,
In the D4 Elect trailer brake wiring thread check out post #450, Strydes has posted a PDF summary. Diode is required Jaycar cat. ZR1041.
You can change 7 pin flat to 7 pin round by matching the correct pins or just get an adapter

Thanks for the info guys. Just wondering with the diode, do you solder and shrink wrap it and should it go near the break controller or near the wiring loom under the tail light?

The job of the diode is to prevent back feeding the CJB from the rear circuit and killing it (read big $$$).

It goes up the back!

I put my 6A diode (purchased from Jaycar) in the lower rear passenger side tail light/storage area (this is where most others seem to have done). There is enough room to solder the diode in place and shrink wrap the necessary wires. All seems to be working well .

Can you shrink wrap the diode itself or just the wires either side?

I am not an expert and if I remember correctly I used shrink wrap up to the sides of the fatter bit of the diode (covering the soldered joints and thereby giving electrical insulation. I then covered the wire/diode/wire section with cloth loom tape. I then placed this wire away from the rest of the loom as much as possible in order to facilitate any heat dissipation.
