I don't have the wiring diagram to hand, but why are you asking? the loom should be plug & play, no wiring required...

i have just removed one of these from a car in the scrappy yesterday and have the loom if you need pics of it or something....i took the clocks that it was attached to just in case they were different from mine.

As mark says it should all just plug in.

All clock sets, except possibly very early ones, will work with the OBC.
I've already replied to this post in response to a PM. Said much the same as has been said above.
I've identified a few of the wires for him, but, as you've said it's just a short loom with a multipin plug on each end, so I've never had occasion to work out what each individual wire is, and my wiring diagrams only refer to the 12 button, and aren't complete.

ive not fitted it yet but it looks a caker judging how easy it came out, the only bit i didnt get was a bit of loom that disapeared away under the bulkhead behind the glove compartment (next to the white multiplug thing)....it was just two wires...blue and a brown one......kinda hoping this will be present on my car or it probably wont work.

didnt get the outside temp guage either cos i dont know where it is....not so bothered about this as its either mild or bloody freezin up here :roll: ....maybe thats what the wee loom i missed is for

the wire through the bulkhead is (on a 12 button) for the code function alarm horn and the temp sensor, which clips into the front left brake duct.
The problem with missing out the temp sensor is that every time you turn on the ignition the ice warning gong will sound and the OBC will default to outside temp, and insist it's - 23 degrees.
