why you taking clocks off?

is it digital dials or not? cause if its manual (where numbers rotate) like a fruit machine its easy to take the cable off. just loosen the clocks off, push the cable through from the other side a bit so you can get your hands in there and see.

then you will see at the end of the cable attatched is a plastic housing. and all you do is squeese the 2 bits of it that stick out slightly and pull it out. simple.

nothing to worry about.
