Looking for the correct Power FC for my 95, I see that I need the FD3S 4 which is for FDs built between Dec 95 and Dec 98. The FD3S 3 is for cars made between Dec 91 and Nov 95. Does anyone know the difference (however small) between the two ECUs? My car was built in Dec95, so I know I get the FD3S 4. Just wanted to know the dif. Thanks, Rick

 

they should both have different connectors going into the ECU

 

All US models use either FD3S4 (which is the current production version of the PFC) or FD3S2, which is the old version that's no longer for sale.

my car is 12/95 and i just installed an fd3s4 pfc and it seems to be working fine, connectors match up.
