I think I might be missing a part in my FD swap. It seems there is a ignition controler of some sort that is mounted on the fender or fire wall. It feeds a signal to the ignitors.



I found a part # on the Mazdaspeed online catalog part # 18-251A or N3A1-18-251 it is described as a Ignitor 1G Coil Trailing. I see nothing for the leading.



Am I missing something here??





Can I use MSD ignition controlers to control my ignitors instead??
