• To ensure the power to run the vehicle, do not remove the AC generator. Use on the
battery alone will make the vehicle unable to run in a short time.
• The wire harness will not function if it is not assembled with the ECU (BN6-8591A-70,
71, A0, A1, A2, G0, B0, B1) of the kit.
• The combination of this wire harness and ECU can only be used with ’17 to '22
models.
•
in advance. Before starting assembly, remove the coupler of the main switch.
• Be sure to connect the Hydraulic unit assy. to the wire harness. The ABS does
not function when using the KIT ECU, but every electronic control does not work
without the connection. Also, change the installation position of the Hydraulic unit
assy. by following the instructions on following pages.
