VW 1.9TDi AGR engine swap 80pin ECU

Hi!

as per the title I've got an AGR 90bhp engine and the plan is to put it in my boat after the trusty but thirsty Volvo Penta petrol lump bricked it. Anyhow, I had planned to swop the fuel pump top for a cable operated pump top from a Landrover 200tdi but the more I think about it the more I want to keep it as is.
The ECU is already bypassed (car starts and runs happily with a metal key blade without transponder chip) but I'm struggling to find a Pinout for the 80 PIN ECU so I can adapt the original VW loom into a standalone loom for the boat. If I have to go through a wiring diagram pin by pin I will but it would save me loads of time if any of you gents had a the pinout.

Many thanks

If it's running without an ECU, why use one?

It's not running without an ecu, I planned to swap to a mechanical pump, but think I'd rather run it with the ecu as intended.

Have you tried googling the part number and pin out? I've found some that way. There's also sites like ecu connections I think it's called.

Done the Google thing to death, tried bosch part number and vw edc15 pin out and vag part number. So I've given up on finding a pinout and I'm making my own from a wiring diagram.
I'll post it on here when I'm done incase it helps anyone else out.

My progress with the pinout

I think this is pretty much it for a standalone wiring harness for the 80pin ECU 038906018 or 0281001845.
To get it to run It'll need....
12V to pins 2, 28, 47
0V (earth) to pins 1, 25, 27, 33.

If anyone is bored and wants to check it that would be great! Hope it's of some use to others trying to do the same.
