Our custom ABS harness allows the Ate Mk 6.0 ABS system from a 2003-2006 BMW E46 M3 to run as a “stand alone system” and potentially be installed in any car, not just a BMW. Most of our customers will use this system to replace a 3-channel ABS system which is inadequate on the racetrack. Our harness will allow the E46 M3’s ABS to work without needing any of the factory wiring harness or dash cluster – it’s stand-alone! The E46 M3’s ABS system is a four-channel high performance system which applies ABS to each wheel rather than a three-channel system like on a BMW E36 that only sends one signal to the rear (and two to the front). The Ate Mk 6 system is currently one of the best ABS systems on the planet. We have used this setup on our own race BMWs with great success.
