spewing to hear Leigh, id hate for a car to be so violated,
regarding the not running right, if you have a wiring diagram for either the safc or car, find the AFM signal wire and join the two ends together, thats the only wire that needs to be cut when putting an safc I in, not too sure about the II but, if you need a hand, give me a buzz, should be able to fix it up for you.
