Ok, since A-L.com is still having issues I'm gonna post this over here. I am looking to install the AEM EMS in my 91 Sedan. I know the only thing that keeps this from happening is the fact that our ignition system needs 6 ignition signals and the EMS ony has 5. So the factory ignition needs to be upgraded. What can I do to upgrade the system. I already know that the G1 wire ends fit in the G2s spark plug gallies. I need input on this so I can get the ball rolling!
