Well i think it was quite easy compared to other cars. This one is with one-point-injection, and the engine bay has lots of room, compared to Civic whick has no hole for fly to.. fly.
For finding the injection signal, i strongly recomment to just open the intake air box, that where the carburretor(or whatever you call it) is, and find where the wire goes from the injector.
On my experience, that where the MPGuino installation guide says "look for 12V", that is the voltage for the intake temperature sensor(NTC resistor), another is the other leg of that sensor, and two remaining, are plus and minus for the injector. You take the signal from the minus of the injector(the one going to the ECU).
THe VSS signal is quite straightforward, it's at the transmission box. Three wires, VCC/signal/GND. Easy to measure.
