This loom is intended to be used with MoTeC's M142 TOYOTA YARIS GR 2020 KIT (#11412).
 
It provides an electrical interface between the Plug-In ECU Kit and the active rear differential clutch of the Toyota GR Yaris. The Diff Loom replaces the functionality of Toyota's OE AWD ECU, allowing the user to define the parameters of the rear differential clutch with MoTeC's Yaris GR 2020 G16E Package in M1 Tune.
