I have done the under-bonnet wiring on my mates car, But when we come to swap over the transponder over to the vectra one we/he noticed that the colours on the transponder plug were different between the astra plug and the vectra do you know what we have to do?
Should we just plug the vectra transponder straight in and wire the immobiliser (Blue/Black) from the x7 plug to pin 7 on the transponder.
or will we have to wire the vectra transponder plug on to the astra one so there all the same way.
Heres the vectra one
Heres the astra one
