Hi

RX8 Alternator does have to small wires 2T and 2I i think, goingo to oem PCM.
How do you wire it up to Haltech's PWM when oem PCM gets removed completely?

Do i need to use both thin wires from alternator, or just one?

thanks

 

I would advise you keep the rx8 ECU at least for the purpose of ABS and EPS. I left mine wired to the rx8 ECU which works perfect

otherwise, you can just let it ground to the PWM and use constant voltage in one wire. Polarity also matters but not harmful. If it's not charging, just flip the polarity.

I don't know what the constant voltage should be, but that shouldn't be hard to find out using multimeter. sorry my car's in pieces now for transmission swap, so I can't test this for you just yet.
