    The tekonsha unit I bought does have the proper connector I just cant find the harness under the dash. Atlantic British shows a connector in this area for A RR sport.

    2008 Range rover electric trailer brake harness, Tekonsha brake controller for ford is supposed to be connected to car wiring under dash, However, I cann not find the connector under the dash. I installed the trailer electric kit from Land Rover, the wiring diagram from the kit shows Trailer module D295?

  • Jeffrey Babiuk Apr 01, 2010

    I have no issue with the main trailer electrics I have installed the wiring kits on 2 of my Range Rovers, I need to hook up an electric brake controller and according to the manufacturer of the controller (Tekonsha./Cequent) there is suppossed to be a direct connection to the Range Rover wiring harness under the dash I can not find the connector. LR part #YWJ500480 the elctric kit for the trailer shows a Trailer brake module in the circuit.

    I will look again I have the 3035 adapter bought with unit. When I first looked for it I pulled

    everything. The air bag center console the works ndid not see it.

  • Jeffrey Babiuk Apr 03, 2010

    Apparently I was trying to find the easy way out instead of relying on my experience with all things British. The 3035 is supposed to fit but it does not. There is no direct connection off the wiring harness. I went back to the trailer socket and traced the electric brake wire( should have done this in the first place!. This wire dead ends in a connector immediately, no possible way for a hookup at the front of this car. After reviewing other sites such as Atlantic British, they sell a wiring harness to fit the brake controller and clearly state for Range Rover sport and LR3 not Range Rover. Oh well, another lesson learned.

I pulled this info from Alldata:

Notes

Trailer Module

The trailer module is fitted to all vehicles and is located in the RH side of the luggage compartment, behind the removable trim panel, adjacent to the rear auxiliary fusebox. The module is required to separate the load circuits of the trailer from the load circuits of the towing vehicle. This allows separate monitoring of the vehicle lamps and the trailer circuits.

The above lamps are connected to the trailer module via direct connections to the applicable lamps. The rear fog lamps and reversing lamps are not directly connected to the lamp units because these lamps must be disabled when the trailer socket is connected.

The LCM communicates with the trailer module via a bi-directional, dedicated serial link. The rear fog lamps and reversing lamps are controlled on this link. The trailer module also uses this link to transmit error messages for the trailer lamps to the LCM.

The trailer module has two modes of operation; sleep mode and normal mode. Sleep mode is initiated by the LCM after a predetermined time. In this mode the trailer module processor clock speed is reduced to a minimum and all loads are switched off to keep current consumption to a minimum. The module operates in normal mode on receipt of an applicable message from the LCM. The required loads and the current supply for bulb failure detection are activated.

The LCM communicates with the trailer module every 2 seconds with a normal mode telegram. If the trailer module no longer responds, the data link to the module is switched low for 1 second after ten unsuccessful attempts to establish the communication. When the LCM switches the data link low, the trailer module is 'reset'. If communication is not established after thirty attempts in succession, the LCM assumes the module is defective and records an applicable error message in the error memory.

If a replacement trailer module is fitted, the LCM instantly recognises it via the data link. Connection of T4 is not required to establish communications between the LCM and the trailer module.

Hope this helps.2008 Range Rover

The harness is build in under the dash however - the wires are not set into a connection specifically for the electric brake. The electric brake unit connection from the dash is a separate connector to be purchased and connected to the dash harness - then the electric brake unit can be plugged into that unit.

So in short they fibbed to you - as they would have no way of knowing what specif brake unit you would be using so how to know what connector to use?

    Having answered as a former representative of the company on both sides here. Please believe me when I tell you - if you drive to the local range rover dealer - they will show you for free where this unit is - if it is there.

I am installing an electric trailer brake controller on my 2008 Ford F- 150 STX pick up truck and I need to know where it plugs in under the dash

Ford's factory supplied brake controller harness end can be found loosely stuffed under the dash, usually just above the driver's right leg. A Ford harness has a rectangular shaped connector.
Simply connect the brake controller harness connector into the vehicle connector. Zip tie the harness wires to another harness to prevent the wiring from hanging down near your feet.
I hope this helps.

How do you install a brake controler for a towing package?

Alot of these trucks have the wiring hook up under the dash or at rear bumper area where you can just plug the wire harness from controler to it, but if not they are simple to wire and then you must level by following the instructions,you would wire it to power and ground then one wire to brake switch and the last wire goes to tow connector for electric brake on the trailer. for more help google how to install brake controller there you will find wiring diagrams and videos.

Brake Light wont go out

The brake lights stay on even when the vehicle has been restored to the "before" condition?!? Now that's strange. I'm assuming the brake lights worked properly before you did anything with the trailer hookup. Is that correct? Do the brake lights work OK when a trailer is hooked up to the trailer lighting harness? Regardless, if the brake lights stay on all the time, there is a continuous 12V to the bulbs to ground. You have a wiring short somewhere in the vehicle. Have you checked the wiring for bare spots (caused by rubbing) or cuts in the wires.

Since the brake lights won't turn off, you have created a continuous path of 12V through the bulbs to ground, regardless of the brake switch operation. If you did not use the plug in type of wiring harness to attach the "trailer plug", then I would systematically undo each wire that you attached to and see what fixes the problem. I assume you know that the Blazer has a trailer connection plug-in location tucked up under the rear bumper. You simply unplug the mating harnesses, plug in the trailer wiring connector, plug in the disconnected harnesses and wha-la you should be good to go.

Hope helps.

Were do you hook up the two wires under the hood for trailer brakes on a 2000 silverado

Sometime around 2000, GM started putting trailering pre-wire harnesses in the vehicle. Your truck may have this harness built in and would greatly simplify brake controller installation. Look under the glovebox and see if there is a wire harness tied off. There will be four wires in this harness, which should be run over to the steering column to use it. Most trailer brake controllers are compatible with this harness.
The four wires in the harness are: Red, 12vdc; black, ground; blue or purple, brake pedal; and brown or white, trailer brake wire to seven pin, four pin, or five pin connector at trailer hitch, if your truck came from the factory with a trailer hitch.
If you are adding the hitch and do not have the four wire harness, the under hood wires from your brake controller are Red, connect to one of the studs under the distribution box cover (the distribution box is on the driver's side against the firewall. Underneath the cover are two large threaded studs which are hot from the battery all the time); and the other wire from your brake controller would have to be run the length of the truck along the frame, tied off in several places, to the trailer hitch connector on the bumper. Follow the directions that came with trailer hitch wiring connector to connect this wire to the proper pin in the connector.
If this has helped you, great, and please remember to vote/comment.
Good luck!

I need to wire an electric brake controller in my truck

you can either wire it straight or gm makes a connector that plugs into the drivers side floor . theres a box down there that has a cover over it and the gm connector plugs straight to it. but be careful because i have seen several times were gm wired it wrong the stop light plug is in the wrong spot.take a test light to ground touch each connector while pressing and releasing brake pedal the one that lights the light, is your stop light look on there connector and check to see if that plug is going to the red wire if not move the red wire to that spot. as for wiring it you have to do it this way. black wire goes to constent hot, white wire goes to constent ground , blue wire goes back to your trailer plug for your electric brake, and red wire as you know by now goes to the stop light.

I do not have power on the aux. terminal in the trailer plug on a 2008 dodge ram. Any ideas?

You have got 7 pin trailer connector that was included in the optional trailer tow package. This trailer tow package also includes an electric trailer brake wiring provision that terminates at a connector located on top of the large body harness connection under the instrument panel to the left of the break pedal, as well as an electric trailer brake pigtail harness and an instruction card that are stored in the glove box when the vehicle is shipped from the factory. You will need to add an electric brake controller of your choice that will plug-in to the harness and that will also give you power on your auxiliary circuit.
