Zetec Engine Wiring
I know this has probably been done to death in the past, but I can't find the info that matches the loom I've got here. This loom seems to have more wires in the plug than anyone mentions on the net.
The usual scenario - 1.8 Zetec into a mk4 scort using Fez Si loom & non-pats ECU.
Got a 12 pin plug that requires feeding with power etc....
Can anyone provide a definitive list of what these wires need connecting to, to work:
Plug:
Pin 1 - Brown
Pin 2 - Green
Pin 3 - Brown
Pin 4 - Black
Pin 5 - Black/Red
Pin 6 - Red
Pin 7 - Black
Pin 8 - Black/Green
Pin 9 - Brown/White
Pin10 - Brown/Green
Pin11 - Black/White
Pin12 - Brown
Any idiot-proof info is very much appreciated as this is the last thing to be done now....
Many thanks in advance,
Steve.

So... the bits I can understand so far...
12Way Plug:
Pin 1 - Brown -
Pin 2 - Green - Connect to Escort Mk4 Tachometer
Pin 3 - Brown -
Pin 4 - Black - Connect to +12v Ignition Switch (with an inline fuse)
Pin 5 - Black/Red
Pin 6 - Red - Connect to +12v (with an inline fuse)
Pin 7 - Black -
Pin 8 - Black/Green -
Pin 9 - Brown/White -
Pin10 - Brown/Green -
Pin11 - Black/White -
Pin12 - Brown -
Anyone else care to add anything? Would like to hear from someone whose fitted a zetec using a Fiesta Si loom to confirm its going to work as I dont want to damage the ECU as they're pigs to find non-pats ones these days.

Have just downloaded a copy of Autodata and Im having a browse....
Time to get the meter out on the loom and see what needs powering up etc...
Am I right in thinking Pin 22 ECU I should wire to the coil (earth side) of the fuel pump relay (to switch the relay on)
