A little update.
First job, let the dog see the rabbit.
There are four looms in the engine bay. The main car loom and three for the engine. Its these three ive started on. There is only two on the <2000 mondeo and other than a couple of extra plugs thats all you need. So Ive stripped back the three sub looms.
I am now tracing back from the ecu the 104 pins
