Hi all,
I'm currently knee deep in wiring and loving it, but...
Have done some searching & can't seem to find an answer...do the live feeds into ECU (perm +12v, pin 55) and (switched +12v pins 71/97) need
to be fused? And/or switched live come from a relay?

The job of the fuse is to protect the wiring. Ford will have calculated the loads and best circuit's to combine but as the wiring is 20years old
now and this is diy. I tend to over fuse my rigs as it also makes trouble shooting so much easier.
1) 1a perm live for ecu memory and pats led
Switched.
2) 7.5a ecu, pats, obd2 port
3) 15a coil
4) 15a injectors, o2 sensor
5) 20a fuel pump
6) 30a Fan
Or something along them lines.

Perfect thanks...I'm half way there already then; fuel pump (and swirl pot pump), fan and O2 sensor done. I'll wire up remaining fuses and
get those circuits completed
Thanks as always for your help!

60 PIN PCM (ECU) Wire Diagram
I have grab information from this forum to find out the wiring of our project LCCT of my son and me.
Therefore my thanks to all the contributors.
We use the original PCM from the Ford Focus (Code TEEM) with 60 pin connector.
Our wiring harness has also a 60 pin connector.
I have made a drawing of the wire harness that I want to share.
This drawing has been based in out build and our needs.
But please remember I am not responsible of what you do with this information. 
The wiring is only for the engine management system and includes information of the PCM, sensors, relays, fuses etc.
I use a self build MTA fuse and relay box.
I hope that this help someone with his build.
Regards,
Carlos
