Im hoping someone can help me out.
My T25 and immobiliser on it.. its a little keypad to the right of the driver console which is conected to a little black box that sits just above the drivers shins and has a selection of wires coming out labelled H,H,C,C,F something something.

Anyway.. the immobiliser is giving it up big time and rarely excepts the code (although once the horns gone off a few times it seems to conenct the battery and you can start the camper) so I want to pull it out but I have no instructions for it and theres no brand name on it or anything...
Anyone point me in the right direction?
Cheers
Pete
