Ecu pinout

Hi
I have not long bought a T4 with a 044 906 022 E ecu, 2.0l AAC petrol engine. It was not running too well when I drove it home so I decided to take the ecu out to check the map sensor. Up on inspection someone has cut the plug off and used crimp pins on each one and then glued Them onto the pins.
I sent the ecu off to a company that have refurbed it, put in a new socket and returned it with a new plug and pins to go back on my loom. The problem is that I have no way to tell which wire goes to which pin number, (19 of them).
If any one could help I would be forever grateful.
Thank you.

You might do better asking on the T4 forum.

I have posted on all the T4 forums I can find. AI answers pointed me to this forum with it having the earlier petrol engine and ecu.
