Thanks robo, after seeing what kind of tool is used I had a dig round my toolbox and found some small pick/hook like things which seem to do the trick
So I've now removed all the redundant stuff I think. All the ecu, sensors, heater, windscreen wiper/washer, interior lights, heated mirror & rear windscreen, and stereo wires are all cut off. I also took out the engine management and power delay relays and their wiring. The engine still starts up fine but I seem to have lost my dash somehow. The dash illumination still comes on via the stalk but none of the warning lights or gauges move now when the key goes to position 2/3. I left fuse 10 in which looks to power the dash (red wire) but not according to the attached image I found (no red wire?). I've left the common feed from the battery (blue/red wire) that connects to fuse 9, although I have removed the fuse itself and the other fuse 9 red wire that went off to the kickdown relay (I didn't have the relay itself but all the wires where there). So I would have thought the dash was still getting power via the common fuse 9 to 10 connection? Any other ideas where I might have taken something out that the dash needed to light up? It's currently earthed on the back of the head and was working fine there until I started removing wires
