Fitting an omex 600 with a megane f7r

[Jaff.]

Can anyone help me with wiring up an omex 600 with the f7r megane coil pack? I have 4 cables coming off the coil pack but only 3 cables coming from the omex to go there (ignition 1 ignition 2 and a switched live feed) so what one am I missing? Am I being stupid and it's supposed to be an earth lol?


Also the 2 sensors on the thermostat housing, 1 is the gauge the other is the ecu sensor. The ecu sensor is easy as its explained by omex how to wire up but how do I get the other one to work with the dials to get a working gauge?


Quite desperate for help with this now so a quick reply will be appreciated


Thanks

the coil pack only needs 3 wires to work, on the CTS it depends how your setting it up is the stock ecu still in place?

What's the 4th wire for then?

No the stock ecu isn't in place, what I have is the omex loom being made with all relevant cables going to relevant sensors etc. and the stuff that needs to go to the car goes into the plug in the engine bay which connects the car to the original engine loom,I've found the cable that goes to the temp gauge in this plug but not sure how to wire it up

4th wire is for noise suppression and as Fred said not needed.

Normally it's

1 - ECU/IGN controlled +12v
2 - ECU trigger Cyl 1/4
3 - ECU trigger Cyl 2/3

Yeah I got them mick, just had a panic attack last night seeing a 4th cable. Having to undo everything would break me lol.
