Starting to get interested in a brake controller. Tekonsha P3 sounds good. Can you be a little more specific with how you routed the blue wire and how/where you tapped into the harness? Pics maybe?

Hi Bob, there are a few brake controller threads on here and on the AusJeep forum you may be interested to check out (can't lay my hands on them at the moment but someone with a bit of internet time would be able to round them up...)
Purchased my controller from here (as well as quite a bit of other stuff- good supplier and I would use them again) http://www.ebay.com.au/itm/TEKONSHA-...ht_2456wt_1217

I had a think about what wires I needed where and ran them all at once, from the battery area under the drivers seat down under the RH side trim and into the tub under the spare, then out through one of the three grommets in the floor there - Anderson plug positive and negative in 6 B&S size twin plus blue van brake supply, while the controller brake switch supply continued across the floor to the tow bar wiring harness where I tapped into near the LH back bin.
The controller I mounted in the cubby. This involves removing the trim around the console (there's a .pdf on trim removal here http://www.wk2jeeps.com/wk2menu.htm ). The controller works great here for me, but if you intend doing it keep your missus away as it doesn't look pretty!!
Wiring to the controller came through the back of the cubby. Tight fit, but it went in. If you leave a bit of wire slack out the back of the cubby it will make it easier to get to the plug at the back of the controller. The controller bracket is double sided taped to the little rubber mat so I can remove it - doesn't move and works fine.
Power feed to the controller came from the battery via a circuit breaker. The controller is powered up all the time but a feature of the P3 is that it will go to sleep when no movement is sensed so no issue there for me.
Earth went straight to the battery.
The 6mm blue van brake feed went back to the trailer socket.
From the cubby to the battery area all the wires were tucked under trim or carpet. Between the drivers seat and the console there is a carpet join that you can get wires down into and hidden. The controller comes with around 500mm of wires from the plug and I soldered and heat shrinked all these up in front of the drivers seat then tucked them all away.
Others have used a Redarc controller so it can be installed in the dash near the fuel cap release but I lke the P3 and happy with how it works. When not towing I close the door on the cubby and forget it.
One tip though - if you are working on the vehicle and disconnect component plugs when removing trim - do not turn on the ignition, or attempt to start the vehicle with any plugs disconnected. The Jeep runs a circuit check every time it starts and will throw a code (or worse, a hissy fit) if any circuit is not complete.
This from experience.
Good luck
John

Re: Towbars in Australia

The good thing about the Redarc is that it can be installed remotely, while only as knob is displayed on the dash, or console.

Re: Towbars in Australia

The Redarc isn't a proportional controller however......my P3 will allow the van brakes to pretty much work seamlessly with the Jeep. I can see the voltage ramping in line with the brake pressure applied. i lke the display options as well.
My experience with other solid state controllers has been that they can be clunky in operation - although by all reports Redarc owners seem to be happy with theirs.
There aren't too many options as to where to put a controller and the Redarc has the advantage of being able to be concealed - hence the effort I put in to mount the P3 in the cubby.
They are both close in price on the web so it comes down to personal preference - both are likely to do the job.

An excellent write-up! Should be made a sticky!

Re: Towbars in Australia

Is it possible for someone with a mopar (best bars) bar to post a close up picture of the cut out in the rear bar. I ended up getting a good deal for a mopar bar and front tow hook, all I have to do now is fit it.
The template that comes with the fit kit seems to rather large.

Cheers
Adamt

Adam, ours has a Best Bars - but I don't have a pic to post unfortunately.
I can offer however that if ours has the cutout by the template (and I can't see the dealer would do it any other way) - that you wouldn't want it any smaller.....
You'll need access to get D shackles to the bar, and the present access to the 7 pin flat plug fitted with ours is tight. Any smaller and I couldn't get the plug in. The issue is that you need to get fingers past the cutout to open the socket door, plus get the plug in at the same time.
I can work it and I guess the reasoning is that people want the smallest and neatest workable access.
Just measured ours - 230mm measured across the trimmed opening. Approx 105 deep

Re: Towbars in Australia

Thanks John47

Thats what I thought, and yes I do want to make it as small and neat as possible, even if I have to move the plug connection.

Again thanks for your detailed reply.

Cheers

Re: Towbars in Australia

John,
Regarding the blue wire from the brake controller to the trailer plug, do you know if it is the sole carrier of power to the electric brakes or is it a signal wire to a servo. I ask because I was wondering if voltage drop is an issue. Also, I seem to recall seeing somewhere that US vehicles have a blue brake controller socket somewhere behind the dash that the brake controller simply plugs into. I take it Aussie vehicles don't get one or you would have seen it? I looked under the dash but couldn't find one.

Hi Bob,
the blue wire that comes from the controller is the sole carrier and has variable voltage applied depending on the output from the controller.
As far as I know the export vehicles don't get the brake controller socket in the dash. Plenty have looked for it but never found. It wasn't all that hard to wire up (my opinion).
I used 4.5mm blue wire (measured outside the insulation) to the socket - personal choice - this size wouldn't fit into the socket so I crimped a terminal and screwed that in. I found it difficult to buy reasonably heavy blue wire for some reason.
Braking force on electric drum brakes is determined by voltage at the magnet so this varies (on my system) from 0 to around 7 volts max locking up the brakes - and all voltages in between. Normal applications with the van would see from 2v to 4v I guess. (the P3 shows this on the screen)
Using these voltages I don't believe voltage drop would be an issue - because the controller should be set up to each individual situation, and each one would see a different controller threshold, accommodating whatever wiring was being used to deliver power to the magnets.
The p3 has 3 different "boost" settings that change the behaviour for more aggressive operation round town for example.
I'm prone to "more is better" however so I used the biggest wire I could readily get hold of - and I have rewired the van brakes as well so I know in my situation if I need to seriously plant the foot on the brake the tug and van combination are going to be delivering their best shot at pulling up.

As John says, it's tight. Then with two shackles and possibly an Anderson plug, you wouldn't want it any smaller. See the pic.

Re: Towbars in Australia

Thanks for the response, I have just finished fitting my bar and made the cut out 145mm smaller than recommended, I think it looks a lot better. I will probably mount the plug on the edge of the bar.
