US-Spec M57 E30/E34/E36 Plug and Play Wiring Loom

This loom was specifically designed for the U.S. market, it's the perfect solution for those, who want to M57 swap their E30, E36 or E34 (E34 loom also works for E32's).

Due to differences in ECU'S (Or DDE Units) our standard PnP looms do not work with U.S. market engines, however, we designed this one, to make the swap as painless as possible.

Interface With The Rest of The Car

No need to worry about non- working instrument cluster. The loom is engineered to keep your cluster working as intended from the factory. However, some additional coding might be needed for the clusters, to correctly display RPM's. Of course, speedometer, fuel gauge and temp gauge (you must use the original temp sensor!) will also work as intended from the factory. 

Other Interfaces

The loom also supports the following:

Automatic transmissions (integrated brake pedal position sensor connector): 

• 6Hp
• 8hp (requires CANTCU or similar controller) 

EKPM 

Cruise control interface*

*requires additional VSS module and STAKL interface

CAN Gateway modules

I/O's

• Reverse light switch input 
• Can bus 
• PWM output for electric fan
• Brake pedal position sensor input ( must use magnetic brake pedal position sensor or Our brake switch converter)
• Starter activation 
• Temp sensor input 
• Additional ignition output for auxiliaries 

NOTE, THAT THIS LOOM ONLY WORKS WITH ECUS'S AS PICTURED BELOW
