Hoping that someone can help?

I'm struggling to find a wiring schematic/pinout for the ECU harness on a MK1 Tuscan.

I've not managed to find this included in any documentation online - I think I've done some pretty extensive 'Googling'!

From what I can work out so far the loom inside the car includes:

1 x ITT Trident 32 Way (28+4) Bulkhead Socket into engine bay
1 x ITT Trident ?? Way Bulkhead Socket (with 4 wires used?) into engine bay
1 x ITT Trident ?? Way rectangular connector
1 x 55 Way Connector (to MBE 941 ECU)
1 x ITT 3 Way Connector (for serial connection to ECU)

The loom in the engine bay (maybe?) includes:

1 x ITT Trident 32 Way (28+4) Connector to bulkhead socket
1 x ITT Trident ?? Way Bulkhead Socket (with 4 wires used?) to bulkhead socket

6 x 2 way Injector connectors
2 x 3 way TPS connectors
1 x 4 way Ignition coil connector
1 x 3 way MAP sensor connector? (Could this be inside the car, connected via the rectangular trident connector?)
1 x 2 way Coolant Sensor connector
1 x 2 way Inlet Temp Sensor connector
1 x 2 way crankshaft position sensor connector
1 x 2 way camshaft position sensor connector (unused)
1 (or 2?) x 2 way knock sensor connector (unused)
[All above 'Junior Power Timer' type connectors]

2 x 3 way Narrow Band Lambda Sensor connector
Oil Pressure Sensor (Ring/Spade terminals?)


Various Ground ring terminals
Connection to Aircon compressor?
Connection to purge valve?

Is there a diagram/pinout out there anywhere please?
