I have bought a HKS FCD for my WRX MY95 and the wire instructions are a bit woollie.

Anyone know which wire I have to cut and which way round I connect white and yellow leads out of the FCD?


Thanks in advance.

You have to wire it into the MAP sensor form the ECU, you can find this on a wiring diagram on threads on sn.

One point worth noting though, when i wired mine in (my93 wrx), i wired the positive to a switched ignition feed, this resulted in the cel coming on if i turned the ignition too quickly, wire it into a continuous live feed and this isnt a problem

Also make sure you have a goof chassis earth, either the earthing point on the ecu or from the battery negative terminal.

Let me know if you can find the MAP wire, and i will dig out the ecu diagram for you
