    Has anyone had brake controller fitted to their VF yet? I am looking for advice before I get one installed. I have heard that there is a factory wiring loom that can be purchased for a brake controller but the dealer I went to did not know of one.

    I have the factory HD bar and harness installed on my Calais sedan.

    Correct me if I'm wrong but do all VF Commodores not come with factory fitted EBC? I'm pretty sure they do as it's part of the ASM & ABS control.

    I think he means electric brakes for a trailer

    Yes, sorry folks, I am talking about mounting and installing a brake controller for activating trailer/caravan brakes.

    I always thought electric brakes were on the trailer (NOT the car) and worked when the stop lights go on

    Electronically operated brakes (as on trailer/caravan etc) require a Brake Controller to be fitted/installed in the vehicle within easy reach of the driver. The most reliable one is made by Tekonsha, the P3 Model. They have to be hard wired into the vehicle electrical system and brake force is applied by the controller that detects inertial activity i.e. when the tow vehicle brakes the controller activates and sends power to the brakes thus applying them. The brake controller can also be manually activated, ideal if the trailer starts to sway or when descending hills etc. tekonsha p3 | eBay

    Thanks Benboy.
    I am looking for anyone that has had one fitted for advice on installation tips for a VF.
    FYI I am converting my caravan from hydraulic to electric brakes.

    For electric brakes you'll need a controller, Tekonsha is a popular choice. It took an auto electrician around 2 hours to install mine (a Tekonsha P2) in a VXII wagon, pretty fiddly job, however worthwhile for the piece of mind. Make sure you take your car and trailer for a test run, I initially had too much assistance dialled in, however it doesn't take long to get the initial calibration right. You could save some money yourself by doing some of the prewiring, especially the long loom that goes from the controller (generally under the dash - it needs to be easily accessible) to the trailer plug at the towbar.

    I have the redarc tow pro and will be fitting it when I get the time. Installation is easy as there is a point in the factory tow wiring loom for a pick up. I will mount the unit next to the battery and may run the remote controler into the cab. It states in the owners manual that a pick up for the electric brakes should only be taken from this point. I am not sure where the pick up is but it will be in the boot behind the trim possibly on the drivers side. The tow wiring loom just plugs in between the standard wiring loom and converts the signal to a standard 12 volts rather than the varying voltage of can bus.

    Towed a few of the biggest new vans up and down the east coast with a 100 series and these things make it a breeze. When adjusted perfect you brake then feel the rigs brakes apply. Towed a monster food outlet thing that required us to fit load stabiliser bars to the Toyota and upped the thing to save the car brakes. Highly recommended.

    I have installed a Tekonsha P3 in my last 2 VE wagons using the factory loom that I purchased as a spare part. I just took delivery of my VF and they have changed the wiring a bit from the VE so the VE brake controller loom doesnt suit but could be modified. The dealer I spoke to also said they didn't have a loom listed for the VF or the required connector.

    I have ordered a new Redarc Tow pro as the remote head will be easier to install and the main unit can be mounted near the battery to keep the wiring short.

    Next to the battery in the VF trailer light loom is a 2 pin connector which has the blue wire for the trailer brakes and the brake light signal for the controller. I havent been able to source the mating connector so may have to cut it off and use my own connector. Does anyone know where the connector could be purchased?
    The only other connections a brake controller needs is battery positive and ground.

    Regards
    Daniel

    Hi all,

    I'm getting a 2100kg bar/hitch package fitted this week and maybe a Redarc Tow Pro (if required).
    If I didn't use a brake controller with a trailer equipped with electronic brakes what exactly happens when brakes in car are applied?
    I'm guessing you get the same trailer brake pressure (mid range) no matter what pressure your car brakes are receiving, only guessing though.
    I've done plenty of towing, but only at work in large trucks with brake controllers so I'm clueless to everyday car towing.
    Also, in regards to what I think Christov (on page 1 of this thread) was referring to, was the trailer sway control that the VF has.
    So what happens when your plugged into a trailer with brakes and maybe have a brake controller?
    Is the electronic sway control sending any info to the trailer and if not would the trailer brakes and controllers get in the road (so to speak) of the effectiveness of electronic sway control that the VF has, for example, if the sway control is bringing a trailer into line using different braking pressures to either 2 axels or 4 wheels (not sure) what info is it sending to the trailer brakes.

    I guess to sum it up, are trailer brakes and/or brake controllers going to interfere with the VF's sway control.

    Any comments and thoughts appreciated from Tow Masters or rookies like myself.

    Yes I think the Tekonsha P3 is the best one, I've seen some articles on brake controllers in a caravan mag and they suggest the better controllers are pendulum type solid state. Pendulum type will mean the controller needs to be mounted such that it's in line with direction of travel and with limits as to angle it is mounted. The Tekonsha P3 needs to be mounted with this in mind, whereas as Redarcs don't have pendulum, you can mount them how you like. No pendulum means the braking output voltage is constant, it doesn't vary with the cars braking, so a light dab on the cars brakes will still have the same braking effect as a hard brake application. The Tekonsha P3, P2 and Primus IQ all are pendulum types. I had a P3 in my SV6 I traded just before Christmas - I removed it from the SV6 and will put it in the SS (replacing a lesser controller already fitted in my VE SS). I found also you can mount a P3 in the forward console space under the vent controls (I put a piece of I think 19mm thick timber under the mounting bracket which I turned downwards and it is a very tight fit, doesn't move at all).

    Hi fellas, i am just about to buy a Redarc and fit it, i found the coupling next to the battery it has a blue wire and a purple which i presume is the brake supply (purple) and brake output to trailer plug (blue wire) i'll let you know how i go

    The VF has a trailer sway control feature which is presumable part of the ABS system. So how does this sway control feature actually work and is it only intended for small in braked box trailers?

    Also, if Holden sell 2100kg towbars, and there a legal requirement that such heaven trailers have a braking system as such, how does VF sway control work with these heaven electric brakes trailers?

    Surely Holden must have something to say on the matter, not those idiots at HCC or the sales/service at the dealership but the Holden technical people that designed the actual vehicle?


    Just can’t believe that there is no Holden technical info about sway control and electric trailer brakes.

    I think that the sway control is part of the stability control rather than the abs.

    My understanding is that when it detects the car swaying, it applies the brakes, but only on one side of the car with the aim to dampen the swaying motion. I don’t think that it attempts to brake the trailer as such.
