    I was wanting to see if anyone had a diagram or a connection on a new wiring harness for under bed? This goes along passenger frame to the front and goes back by fuel tank. There is also a abs wire that ties into this wiring. Had an issue with squirrels or? Chewing on some wires. Now my abs and traction control lights are on. I spliced what I could see last year and alarm lights went out, but they are back along with a flashing 4 high and 4 low. Also brake pedal is really soft now? Any help would be greatly appreciated. Thanks

    @1lowlife could probably find the wiring diagrams you are looking for and help steer you in the right direction for diagnosis.

    Welcome to the forum.
    You can find wiring diagrams here.
    Ultimate TUNDRA Wiring Diagrams Collection | Toyota Tundra Forum

    Pull up the 2014 diagrams, put 'TRAC' in the search, and you'll get 10 pages of the circuits and connectors for ABS , Auto LSD , TRAC , VSC.

    If you type 'Rb1' in the search box, one of the connectors for the rear wheel speed sensors, you'll be able to see the entire wiring diagram for that circuit.

    Basically the same, be it CrewMax or double cab.

    Looks like it’s all 1 harness from the front all the way back? Anyone have a site or part # to order the harness? Thanks in advance.
