Does anyone have the wiring diagram for the FC3S?
The English version that shows up on google does not have the FC3S.
The Japanese version that came with my booklet does not have the FC3S.

I think this is like the deal with the old school Apexi S-AFC, where you could only find the wiring for the FD3S, but not the FC3S.

So, anyone happen to have a hold of the S-ITC wiring for FC3S? Called Apexi twice and they were suppose to fax it to me...

 

You can use the 91-95 FD wiring info on page 26 of the S-ITC instructions, and just match up to the correct pins on your S5 ECU. It looks like this unit just intercepts the three CAS wires at the ECU, and also has power and ground connections:

• [*]
• [*]
• [*]
• [*]

Look on page F2-8 or F2-77 of the S5 FSM for the ECU pin-out.

It's easy when you have the S5 and S6 wiring diagrams handy.

 

Thank you!! I will let you know how it works this weekend.

 

what about s4 wiring?
