Hello.
I have a 1.6 miata 97´s (european version) with a 1.6 94 engine (laters engine 1.6 in USA).

Well.
I am investigating about delete the AFM in my car with the PnP MS and the sensor in the intake.

But, refering to wiring i have a terrible question.

there is a light green wire that runs in the AFM and in the MAIN RELAY (FUEL RELAY) (and in the Diagnosis conector) that if the green wire is not conect to ground (with the AFM open) the Relay do not works.

Well, that wire is not conected with the AFM deletion then that wire is not ground, then the Fuel pump should not works. That is a security in the car, for in case of accident, the AFM closes because the engine stops and the Fuel pump stops.

Can any body explain me how is posible that it works????
