im sure its possible haha, on the mk1 i just took a green wire to the coil, black wire to earth and a red one to power it was actually that easy, but i havent even looked in the bay of the mk3.5 yet so no idea lol

You can take a feed from the EDIS I believe. I'm pretty sure that's what we did when the tacho packed up in the 1.3 HCS Fiesta a friend had for a while. Was a good few years ago though
