Hi,

Was wondering if there is a way to convert the Fab9 coil on plug kit to sequential spark. I have had the kit for a while and have been using the PNP harness. I see they have a harness available but I want to make my own. I'm only confused because the coils that are supplied with the kit are 2 pin rather than the Toyota coils with are 4 pin. I suppose this has something to do with the coil driver? If so, how would I adapt the wiring to it?

Thanks

 

I believe the Fab9 COP kit uses a standard Bosch ignitor, part# 0227 100 211 (can you confirm this?)

Here's the wiring diagram:

My guess is ignition output from ECU 1 and 2 are spliced together in the Fab9 harness with 4 and 3 respectively. You'd have to cut these splices, and wire them to your additional coil drivers at the ECU.
