You can just use one of those (T-taps?) You clamp it to the wire and then it allows you to plug in a connector without having to cut or strip. Radio shack would have it.

As for the injector lead, you may want to ask around in the forced induction section. They problably have more knowledge about tinkering with the injectors and such. I don't know what kind of signal the arduino is going to look for to do the calculation. I guess taping into one of the injector wires would be enough because I would think they would all be receiving the same signal for the same amount of fuel so that signal can be deciphered and multiplied by 4.

I just thought of this. There is probably a some kind of injector signal at the obd2 port which is right behind the plastic cover under the steering wheel by your right knee. The Scangauge does all these functions of this MPGuino and more by only plugging into the obd2 port. Maybe you can get a pinout for the obd2 port somewhere.

My other thought would be off of the ecu somewhere. Again, maybe the forced induction guys would know.

Good luck. Looks like a fun project. I might attempt it but I got my scanguage already.
