My other half's 96' Fiesta Flight had a picture of the car. I bought a set of clocks and expected to have to run an extra wire to the coil but it already had it. The clocks plugged straight in and the revcounter just worked.

This is the first time I have ever had this with a Ford - I've always had to run an extra wire in older cars. It could be because 90% now come with a revcounter that they no longer bother having two different looms.

Point is - you might be lucky and they plug straight in
