Hi,

Searched the whole forum but came up empty so...

Just retro-fitted a cruise-control stalk to a friend's Corsa C.
It's 2006, pre-facelift (I think) with Z13DT engine. Has CDR2005 and no CIM module which makes me think pre-facelift.

Wired in 4th wire from stalk to BCM pin 2.
Clutch switch changes between active / inactive.
Brake switches 1/2 change between active / inactive.
Cruise control voltages vary nicely as I press I/O/R
Cruise control "present" programmed into BCM.
Possibly some other cruise control programming into another module (instruments?)

In engine measuring I consistently get "Cruise Control Tip Switch" "Not Programmed"

Variant Code index for BCM is 11 / 5.

Instrument tell-tale test shows cruise-control LED not fitted but reading around I get the impression that shouldn't stop it working? (I have LED on order anyway).

Any ideas? Can't find a list of variant code indexes for BCM so wary of trying other values willy nilly!
