The Epic Motorsports standalone wiring harness makes upgrading your racecar to an E46 M3 ABS system or removing excess wiring from your E46 M3 a relatively easy job. This professional quality harness plugs directly into your customer-supplied 09/2002+ E46 M3 ABS unit and wheel speed sensors. It requires 5 additional wire connections to have a complete running system. Our harness also includes a pin for OBDII plug diagnostics and a warning light to indicate if something is not functioning properly.

Kit does not include speed sensors or ABS unit.
