With only 2 weeks to go to the RR mapping session I really need to get the new 2.3 Duratec and new Emerald up and running in the next couple of days. I've got the Emerald wiring loom in and all the sensors attached but can't figure the wiring at the ECU end - not helped by the fact there doesn't seem to be a wiring diagram in the user guide
So when I removed the old Webber Alpha ECU and loom I marked up 2 wires under the dash as follows:
1 - Switched +ve for ECU supply
2 - Tacho ECU supply
I also have a black wire next to the battery with a bullet connector on it and I've marked it 'Fuel Pump -ve from ECU?' so obviously I wasn't sure what it was when I disconnected it 3 months ago!
Also there's a round connector comming off the main ECU end of the loom which has 7 wires comming off it (green, yellow, white, purple, red, red and orange - without any connectors fitted) and I have no idea what they're for
And finally I have a connector call BARO which I assume is for at atmospheric pressure sensor which I don't need?
Ideally I'd like to be able to compare my wiring with another Emerald & Duratec car - CAN ANYONE HELP PLEASE 🤔 🤔
