@ Jon

Thanks, but that's another ignition module as the std Cosworth one.
I'm going to use the std module, and that one is having 2 wires connected to the ECU. Or am i missing something in that diegram you were giving?


@ White 4x4 cos

Already found this indeed:

Webber/Marelli’s IAW045 and IAW048 ECU connector wiring
1 - Ground
2 - O2 sensor (IAW048 cat model)
3 - Crankshaft RPM sensor (-)
4 - Crankshaft RPM sensor (+)
5 - Camshaft Phase sensor (-)
6 - Knock sensor (IAW048) (-)
7 - Cannister (IAW048)
8 - Diagnostic
9 - n.c.
10 - Main relay (-)
11 - Gnd ref. sensors (-)
12 - ECU warning light (-)
13 - Service Connector (-)
14 - Service Connector (-)
15 - MAP sensor signal (0-5v)
16 - Wastegate control solenoid (-)
17 - Throttle position sensor (0-5v)
18 - Injector 4 (-)
19 - Engine ground
20 - 12V (main relay)
21 - Air conditioner signal
22 - Knock sensor (IAW048) (+)
23 - Camshaft Phase sensor (+)
24 - Ignition module (amplifier) out (-)
25 - Ignition module (amplifier) out (+)
26 - n.c.
27 - Diagnostic
28 - Fuel pump relay (-)
29 - Water temperature sensor (0-5v)
30 - 5v sensors (+)
31 - Intake air temperature sensor (0-5v)
32 - Injector 2 (-)
33 - Injector 3 (-)
34 - Idle valve solenoid (-)
35 - Injector 1 (-)



But this still doesn't make sense to me, because the module have it's own ground ( first to mae cooler and from there to engine ground), so why does it have 2 wires to the ecu???
And i assume i need them both to make it work with a stand alone system isn't it?

Somebody?
