Parts included in photo 1 (1B harness shown). Note bundle of red wire which needs to be joined to the blue wire on the main module, if you wish to hook up the reverse gear override.
Notes:
1. Zip tie the accelerator pedal harness out of the way, otherwise it may rub on the sharp metal edges of the pedal mount and also against the brake pedal arm.
2. I cut off the OBD connector on the supplied harness, and connected the red wire into this 7.5A constant 12V source in the fuse box. Obviously tap into the side of the fuse which is protected by the fuse, so that if the ETC shorts out you are protected by the fuse. Ground is just via an eye terminal onto the fuse box mounting bolt.
3. Behind the kick panel in the top 20 pin connector (its length is parallel with the ground), pin #16 (brown/yellow) is the 12V wire which is hot when you are in reverse gear. This is connected to the reverse override wire on the ETC harness. This wiring colour is relevant to MY04 but likely many later models, however as always please check with a multimeter first.
4. Zip tie and tape around the main module adds stress relief for the 3 wires which are simply soldered to the PCB inside the casing. Also it allowed me to zip tie the module through that zip tie, to a factory harness to stop it moving around.
5. All done
