M57 LOOMS

Simplify your transmission swap with the HOUSE OR TORQUE purpose-built standalone wiring harness, designed to integrate BMW’s ZF 6-speed automatics (6HP26/28) into custom vehicle applications—from Land Rover Defenders to Transit vans and beyond.

Key Features & Compatibility

✅ Direct Connections For:

• ZF 6HP26/26X (E53 X5)
• ZF 6HP28/28X (E70 X5)
• Shifter, Engine ECU CANBus, and plug-in CANBus resistors

✅ Universal Design:

• Extra length for versatile fitment (Defenders, Transit vans, etc.)
• Includes +12V, ground, and ignition connections

This HOUSE OF TORQUE loom covers the wiring side only, the CANbus must still be connected to a compatible ECU or controller.

Technical Notes

• Skill Level: Requires basic automotive electrical knowledge for power/ground connections.
• Included: Harness, CANBus resistors, and downloadable fitting guide.
• Not Included: Transmission, shifter, or vehicle-specific power taps.
• BRAKE SIGNAL CONVERTER required when retaining the original brake switch, unless suitable brake-signal conversion has been already sorted. SEE HERE

Whilst every effort has been made to provide detailed instructions to make the loom as straightforward as possible to fit, it still relies on a reasonable working knowledge of vehicle electrics in order to find and safely connect to power and ground sources. We have included the fitting instructions below to aid your judgement.
