Great post. The more detail you could provide, the better. For example, resistor values (before & after) and placement. I know it's probably too late to get photos of these details, but it would be very helpful for anyone else wanting to pursue this. ECU specifics, switch part numbers, identification of wiring harnesses (such as wire colors) and connector descriptions would all be helpful.
Congratulations, and thanks for sharing.
