Do like i did. Sorry for the lack of pictures. I used landline phone wiring and plugs. I hard wired a phone wire (4 wires per line) to power, ground, VSS and injector signal at the ECU location and ran the wire through my dash out to the instrument cluster and put a female end phone line connector onto it. I then made a short pig tail with a male end phone connector on it and wire that to the MPGuino. I then plugged the two connectors together and tucked them under the gauge surround so you cant see them. This allows me to unplug the MPguino whenever I want to like when I put it in winter storage and I dont want my battery to go dead.
