I have been searching all over the Internet trying to find a wiring diagram for the pin outs on the stock wiring harness. I know they must exist because other people have built these units but i cant find any mention of them. Dose anybody have any information that may help in connecting the two boards.

also the n52 board has a place for an optional PWM IAC control which i think i need for my s4 but none of the components where supplied to make the optional circuit. dose anybody know if i need this circuit and if so what components i need to buy to fill it in. specifically they are labeled.
Q1A, Q2A, R5A, R6A, R7A, R8A , D2A, D1A

Thanks in advance.

 

You can find them in the Emissions control section of the factory service manual.

Yes i did eventually find them. It seems they where not scanned properly in the fsm i downloaded. I did find them in my hard copy. my hard copy got soaked in oil so it's not my first stop for info.

 

I use the ones from teamfc3s. Those are pretty good quality.

The components on the adapter board are for some other applications, mostly Toyotas and Mitsubishis. None of them are needed for an RX-7.
