I'm in need of a bit of info. Does anyone know what the pin numbers are at the ECU end that the cranksensor connections are. The system ins the Simtec 56.1 fitted to a 94 Calibra

Only this,and i cant remember who done it either so cant give credit to them and dont know if its any good for your cause either.

Cavalier/Calibra ECU plug pin assignment
--------------------------------------------------------------------------------
Just stumbled across this information in TIS. A few interesting bits there regarding TC - looks like there is also an allowance for retarding fuelling/ignition as well as induction. The alphanumeric codes (e.g. K20) are shared by the Haynes wiring diagrams.
Looking at the plug face on, the pins go:
38-55
20-37
1-19 (this is the row with two more pinholes than the other two)
I still haven't found what I was actually looking for in there though.
1 - Ignition signal to ignition coil final stage K20/Ter.1
2 - None
3 - Ground pulse, fuel pump relay K68/Ter.85b
4 - Ground pulse, idle speed adjuster M33
5 - Ground pulse, controlled canister purge valve (fuel tank vent valve) Y34
6 - None
7 - Signal lead, hot film mass air flow meter
8 - Signal lead, cylinder recognition Hall sensor P47/Ter.2
9 - Signal lead, odometer frequency sensor
10 - Separate ground for oxygen sensor P32
11 - Signal lead, knock sensor 1 P46
12 - Voltage supply from TC motor P34
13 - Diagnostic plug terminal B, X13
14 - Ground for injector final stages
15 - Ground pulse for injector, cylinder 5 (C25XE)
16 - Ground pulse for injector, cylinder 3 (C20XE)
17 - Ground pulse for injector, cylinder 1
18 - Voltage supply for fault memory (permanent +ve Ter.30)
19 - Ground, electronics
20 - Ignition signal to ignition coil final stage K20/Ter.7
21 - Ignition signal to ignition coil final stage K20/Ter.3 (C25XE)
22 - Ground pulse for engine telltale (ECU light?)
23 - Ground pulse for EGR valve Y18 (C25XE)
24 - Ground for final stages, controlled canister purge valve (fuel tank vent valve), engine telltale, idle speed adjuster, fuel pump relay
25 - Ground pulse, AC relay 3 (C25XE)
26 - None
27 - Voltage supply, control unit Ter.15
28 - Signal lead, oxygen sensor P32
29 - Signal lead, knock sensor 2 P46 (C25XE)
30 - Ground, air temp sensor, engine temp sensor, TC motor, hot film mass air flow meter, knock sensor
31 - None
32 - None
33 - Ground pulse for injector cylinder 6 (C25XE)
34 - Ground pulse for injector cylinder 2 (C20XE) or cylinder 4 (C25XE)
35 - Ground pulse for injector cylinder 4 (C20XE) or cylinder 3 (C25XE)
36 - None
37 - Voltage supply for control unit from fuel pump relay K68/Ter.87
38 - TC input signal active
39 - Variant coding (?)
40 - AC compressor input signal
41 - AC readiness switch input
42 - Transmission coding, MT ground
43 - Signal lead, tachometer
44 - Signal lead, intake air temp sensor
45 - Signal lead, coolant temp sensor
46 - Ground pulse, fuel pump relay K68/Ter.85
47 - None
48 - Ground, inductive pulse pick-up
49 - Signal, inductive pulse pick-up
50 - TC input signal, ignition injection cutoff (funnily enough the Haynes diagrams show this not being connected to anything)
51 - Load reduction ignition retard from transmission control unit
52 - None
53 - Signal lead, TC motor P34/Ter.3
54 - Output signal, TC motor for transmission control unit
55 - Diagnostic plug pin G (bidirectional data lead)
