Hey guys whats up, well i bought the S-afc from a guy on evo, he had an evo, he sent his harness from his evo with it, ju thougth i would give it a try but the harnesses dont fit, does anyone know what i have to do like go to mitsu an buy a new harness or what do i do to hook this up to my ecu so i can use it, I know people with RA's already have the s-afc's can u help me anyone out there, thanks

I don't understand.... he sent you the Safc's harness attached to the evo harness? If thats what he did then you need to cut the Safc wires off as close to the evo harness as possible, and wire the Safc to your ecu.

i can just splice it right into my stock ecu?

Thats how you hook up Safcs... at least SafcIIs.
