    I need to add a trailer brake control to my 09 TRD 4 door 4x4, is the Taco pre-wired for a brake controller?

    If you have the tow package then it's pre wired. There's a harness Toyota gives you with the truck that plugs in behind the drivers kick panel that the controller plugs into

    Any recommendations on a brake controller that works particularly well with our trucks?

    I bought my truck used, but it does have the tow package. I think I found the harness(five wires in a white connector) but i don't think i have the plug that goes into it. Do you have a picture of the wire harness/connector?

    You have all you need other than a trailer brake controller and some butt splice connectors.
    Look in your owners manual, it shows where the white plug plugs in under the dash.
    Then, the manual that comes with your trailer brake controller will tell you exactly which of the brake controller wires go to which wires on the harness. Connect the wires accordingly, plug the controller into the truck, and away you go..

    You can check my hidden install of a simple brake controller here: http://www.tacomaworld.com/forum/2nd-gen-tacomas/177363-hidden-trailer-brake-controller-install-pics.html
    Its a much simpler unit than the prodigy mentioned above, but has worked great for me and takes up no space compared to other units that wouldn't fit where i installed mine.

    New to the forum, but owned my taco since new in 07. I have a dealer installed tow package so I only have the four flat connector. I just took my truck to have a brake controller installed and they said that it will control trailer brakes with a 4 flat and an adapter. I have read your forums and u say it can't. I tend to believe you guys. Any suggestions?

    No it won't you'll need an extra added wire and a 7 pin socket.

    If you order a brake controller and you get the "Toyota harness" with it then you don't need butt connectors or that glove box harness, it will be plug and play on a factory tow package truck, no splicing needed.

    I've got a Hayes G2 accelerometer based controller. It matches the truck nice and works really well. The output screen is nice and it's easy to adjust. Has a volt meter in it too.

    If you have the dealer installed flat 4 tow package you're going to need to bring 2 wires from the front of the truck to the back and add a 7 pin plug-in. One will be from the battery to the 7 pin plug for accessory power which will charge the trailer battery for safety brakes and can do other stuff. The second wire will come from the battery to the brake controller, then from the brake controller to the 7 pin and this will control the brakes.

    The other two you need to hook up the brake controller are a ground and a brake lights switch, those should be active in the factory tow harness plug.

    Whoever was going to install your brake controller in exchange for money and thought you don't need a 7 pin plug or 7 pin wiring shouldn't be doing any electrical work on your vehicle... at all.... ever.

    i am still trying to locate where the factory tow plugin goes. my owner's manual has a cheezy drawing that indicates it is below and to the left of the steering wheel but i don't find anything obvious. i pulled the piece that hides the fuse box but i don't see any receptacle that could mate with the plastic plug.

    i see lots of wiring behind a panel just to the left of the foot area. is that where it is and i just need to remove that piece to access it?

    any help appreciated. i am sure i should see it but i just don't!

    You may want to check with the 1st gen folks. Toyota may have changed things a bit since MY1999.

    FWIW, the plug on my pre-wired 2012 was buried and taped behind the harness. It would've been much easier to find and connect if Toyota had added 2" to the sub-harness.

    thanks much everybody. as you said, on about my 4th trip under there i finally found it wrapped in a big bunch of wires and barely sticking out, but at least i found it now.

    getting my big old broken self and old arthritic hands in there to plug it in is going to be fun!

    Put some towels down to pad the door sill and floor, or find a kid to do it. $5 for them to plug it in until it clicks sounds like a great deal on both sides.
