cool head

So I have a 1.6i cvh Xr2i fiesta mk3 and i have put a 1.8 zetec from a Xr3i mk5 escort in the car. Now I'm struggeling with the engine loom. I have the loom from the Xr3i and the one from the 1.6i cvh. But some of the plugs and sockets in the xr3i loom are ofcourse different from the Xr2i and so I'm trying to find wiring diagrams for both the engines so that I can trace the pins in the ECU to their function, compare them, and hopefully in the end add the needed wires/ change the needed plugs.

Anyone know where to get the diagrams?

Also if anyone got a better idea.. please tell me
