Have removed cluster and the complete wiring cable without cutting any wires.
This requires taking the fuse box as a whole unit. I did it without removing the dash board. Took the cluster out with speedo cable attached. This was done by disconecting at the transmission and passing it through the bulkhead. Retrieved the fuel sender, water sender and oil sender. All took 2Hrs. Need to remove the glove box and kick plates to gain access to the heater cables. All looks really clean. Ready for the transplant. We removed the switches to headlights and turn indicators on top of stearing column and it comes away with easy colour coded connectors. Also the wiring swatch comes away from the steering column ie ignition switch by a colour coded connector. All that is needed is to cut a few wire ties that connect the cablling to the body bulkhead.
Transplant ready to go. Keep you posted. Have a feeling labeling the cables on the receiving car will help in the installation of the donar cable. Have wiring diagrams of both at the ready. Can't do more than this, so fingers crossed. I have power windows so I'm going to check how this feeds to the fuse box.
It must be independant of the accessories ignition switch as the windows are opperable with car completely turned off.!!
