the harness is similar in concept to the gsl-se harness, BUT it goes to the other side of the car (left instead of right), AND you need the jdm 12a ecuS

thats right the 12at has TWO ecu's. one for the injection, and one for the emissions, and they share wires.

Nope, the fuel part is separate from the rest. The spark/emission crap does share wires, and is totally different from other RX7`s. I know, i just pulled mine out of the car.

If you dont have the ECU, dont bother, get a standalone. Its better anyhow.

12at

Hey mate , i just used a MT4 microtech fuel only system to run mine and retained the standard dissy for ignition.
I later changed to fuel and ignition using FC upper and lower mani's, CAS and a microtech LTX8
