s4 should say N332 or N333 on it.

the reason i ask is i bought a hks PFC FCON, and the guy said that it was plug and play for S4 Turbo II, i get the thing, and it seems to be the wrong harness for it... i assume it is for an S5. The ECU's for S4 and S5 wouldnt be compatable to hook up would they?

they will not connect, S5 have similar plug pattern to the FD.

The harness will need to be solder on or splice on like the SAFC if i am not mistaken.
