This video has specific details about my COP setup. I'm sure that this is only one of a number of ways that this can be done, but it is the way I did it and it works. I would be interested in hearing about other setups if anyone has done it a different way.
Correction: I noticed that the wiring for the coils in the schematic is wrong. The common side of the coils should be connected to the 12V supply, not to ground as I show in the video.
Addendum: The trip computer mileage reading can be enabled by connecting one of the injector channels to the input of the interface unit located in the boot. I'll work up a shout video to show how it is done.
I'd also be happy to hear any questions or comments.
