These two sensors are virtually impossible to mix up on standard looms due to the length of wires! Sorry to hear your pain sounds like you have bought a right lash up!!

However don't get too upset this can be fixed for about £15and a load of your time and patience. Get a multi meter from maplin and a wiring diagram from the good old haynes manual and buzz the wires out individually from where the are back to the ecu pins. The haynes diagram will then tell you what the wire should do. I made my own piggy back enging wiring loom using this method!
