Pulling my hair out with my van,
I need to wire up the management light to try and work out what going on. Which wire is it?
Much help would be appreciated.

Thanks for that, I borowed a tech 1 today plugged it in but it wouldn't connect, going to try and wire up light, seem to remember a blink test or something,

Yep if you earth out either the brown yellow or brown white (can't remember which) it should make the diog light flash

Haven't been on for ages going to have a play with the van this week,
I need to wire up the light in the first place what colour wires are they so I can at least put a bulb in

There is a space on the digi dash for the light, its the std symbol of an engine with a lightning strike through it iirc, the wire colour is brown with a blue trace to one side of the bulb, you need a switched positive feed to the other side. The diagnostic plug wires you need are brown/yellow, brown/white, red(+ve feed) and brown(-ve), all the others can be ignored, this will allow you to connect the car up to the Tech 1 computer at any vaux dealer for trouble shooting puposes.

from glenn

so I guess brown with a blue trace and positive to other side so the ecu must earth brown with blue trace
