Follow me on this you guys.

My ignition is a Ford EDIS system off of an Escort. (Don't laugh it works) Wasted spark, no dizzy and a 2 coil 4 tower coil pack. The problem is that the 914 tach is triggered off of the negative side of the stock coil and it won't work with the EDIS system.

So, I snagged an Escort tach at a pick and pull and I'm going to swap the guts into an extra 914 tach. I just want to verify the connections. It has 3 connectors. Ground and signal in are self explanatory. The 3rd one is labelled B. This has to be switched 12V, right?

Thanks

Dave
