Thanks Mick, again much appreciated!!
The mistake I've made is that I've fitted a 2nd-hand loom which has had a few bits stripped out already so I don’t know for certain what's actually working or not. The car appears to be running fine and everything seems to work perfectly, the only 'problems' I have are the handbrake and STOP lights which can hopefully be sorted by grounding the handbrake wire and also the battery light. The battery appears to be spot-on and is holding charge and is being charged fine so again I think its probably just an issue with the wire to the clocks. If you were able to find which of the wires in the two plugs in the back of the clocks relates to the handbrake and also the battery I would be really grateful. Thanks again, Mark
