Hi Chris,
I have my car booked in at an auto electrician on Saturday morning (in Kingswood opposite the Cemetary next to the mechanic with the big blue fence). He fixed my driver-side electric window at the beginning of the year and the mechanic next to him installed my Bosch 040 about the same time so between the 2 I don't think they will have any issues finding the correct wire. I'm getting a kill switch installed at the same time, should cost me about $100 all up.
If you work out which wire it is let me know eh?
I tried adjusting the idle screw as a temporary fix only to realise it has a bolt to stop it from moving itself (I didn't have the right tool / time to adjust the bolt then the screw), But have noticed that my car is revving higher when putting the foot on the clutch so not sure what is up their because the screw can't move without the bolt being adjusted first.
Edit: You can come down to the electricians whilst im there if you wish or I will just let you know of the outcome afterwards.
