    I assume the car is still going to use a distributor?? If so, just swapping the wires on the cap will take care of the ignition portion. Then, if you are going to be using sequential fuel injection, you need to find a pin-out diagram and swap the injector driver wires for 5 & 3 and 4 & 7.

    Hope this helps.
