leading coil/ignitor wire identification
hey guys,
am trying to figure out what the black wire with female bullet connector is used for on the leading coil. am going to be using it on my FB so need to make the corresponding wiring harness on the car. couldn't find anything in the wiring diagram myself. thanks for the help.

Rotaryevolution...just to make sure, the coils/igniters are grounded simply by them being bolted to the car, is that correct? I've made a bracket to mount them in my car so if that is right, I'll need to remove it and make sure I have good contact. tia

If you don't have a factory rpm tool to check that pin, you can use an automotive multimeter. Harbor freight has some for 20 bucks or so (although no one there will have any idea what you are talking about). You can adjust your idle to dead on with it using that pin.

the tach signal comes from the brown wire off the FC trailing coil iirc. i don't recall which color wire that is on the actual coil side since they change colors after that point. you could get the tach signal from that bullet connector on the leading coil but IMO you don't want to lose that coil, so i would avoid it if you can.
