I have a G3 I am putting into a 91 (Series 5) RX7. I am rather confused about how to wire the trailing coils. I am setting it up as wasted spark on the leading coil so I need to wire IGN2 to the trailing #2 and IGN3 to the trailing #1. That seem simple enough, but what I can find on the trailing system says that the two lines going to the coil are IGNs-T (ignitions select trailing) and IGNt-T (Ignition timing - Trailing). So how do I hook up the link to this system or do I have to change out the ignitions system as well. THanks for the help.
