I'm trying to fit an Omega 3 litre ecu into my Cavalier 3 litre and not been able to start it.I have the key and transponder supposedly from the same car but get code 145 from the ecu,immobiliser error.On scanning the Haynes manual wiring diagram, there is an extra wire which the cav doesn't have from the transponder from pin no1 that goes to track 937 which seems to go to the "anti theft control unit".There was no voltage coming out of it when cranked and earthing this made no difference to it, but am a little bit reluctant to put 12v to it in case I fry it.Does anyone know if this should be a 12v feed?
I think I have a later car ecu judging by the number of wires coming out of the transponder.
