trailer break controller

04turbogurl · 07-29-2005, 03:33 PM

Has anyone installed a trailer brake controller in their Baja?
I have a 12x7 cargo trailer that has trailer brakes and I am installing the controller next week sometime. I already got the tow package but it was a 4 prong plug and I need a 7 (because of the brakes). I was wondering if anyone has done it yet to give me a heads up on anything. I will keep everyone posted as it goes.

I have to do this - its "brakes" not "breaks".

I really hate myself sometimes.

It's "it's" not "its."

Touche.

I am just barely bright enough to understand how challenged I really am.

(I said I was sorry)

I, too, am wondering how to adapt the wiring to a 7-way plug!
I would imagine that if you went to an RV dealer, they would have the plug you need. Just wire it up as per the instructions with your trailer, (if you have them) and match up the wiring.
When I installed my hitch, I looked at the harness that went into the box to make it a 4-way wire installation. Seems like an easy fix to make it a 7-way.
Check your local NAPA, Advanced Auto Parts, Pep-Boys, etc., and see what they might offer.
Good luck!
Keep it under 90, folks!

Kelly,

It's not that hard at all, really. Most of the 7 pin connectors are easily-obtained from Boater's World or Camping World.

Don't buy cheap; they corrode and short, and you don't want that. Cheap doesn't mean inexpensive, if they fail.

If you have a problem finding them, let me know; I'll get some links for you.

The wiring instructions are usually printed on the box/package, but it's actually very easy. Just remember which pin position you pick for the Baja, and mimic them on the trailer.

I wire up brakes (breaks, for those above the Mason-Dixon line) and RV supplemental braking system with these connectors all of the time, and they are really easy to use, as long as you're paying attention.

Trust me when I tell you this. Before connecting ANY power, get out the ohmmeter, and check each and every circuit for continuity, from end to end.

A short on this circuit can feed back, and take out headlight switches, etc.

If you hadn't checked, Subaru is very proud of electrical parts.
