Just bought an Apexi turbo timer off ebay, quite cheap as well, £63 all in brand new. Its got 2 wires that go to ignition 1 and 2 positions. I'll meter these when I get to them but does anyone know the colours I should be looking for from the barrel and how best to access them. Couple more questions:
Where is it easiest to pick up oxygen sensor wires?
Does the install affect the alarm, ie can you arm while engine running?
My cars an '02 coupe turbo

The car daesn't have a position 1 as such but the vauxhall asseccory wire is RED

From what I remember all other wires are Black apart from the starter wire thats Black/red

From what I can remember, the main incoming power to the key switch is red, then all the outgoing ones that you are concerned with are black wires (sorry!)

A case of getting a sharp pin to spike into the wires and a multimeter to find the right ones :?

Cheers Steve. All black wires then :roll: , just have to see which one goes live at each ignition step.
Does anyone know anything about oxygen sensor wire colours and best place to pick em up.

If I can wire up to this it gives me the 'full auto' functionality, so it adjusts the wind down time depending on previous driving...... I think :? , and some other trick features, or I could just not be such a tart and set a time.

Legoman i might be interested in getting a timer myself one day maybe you should make a install guide :)

The auto run down function doesn't work on my car. It works by monitoring the engine RPM, but I couldn't get it to work on the Astra, because the timer needs to pick up the spark signal in the wiring. The Z20LET uses on-plug coils, so this can't be detected. It's not a major problem, I just set my timer for 2 minute rundown and it does me fine
