Well its finally all done. Had to do the following:
1. Replace Ignition switch
2. Install Ignition Saver Modification
3. Replaced Blower Motor Resistor
4. Re-wired gauges to passenger side fuse block with 'Add A Circuit' taps
5. Tidied up the wiring under the dash with zip ties
I need to replace the heater core and install my wideband kit so I can do a write up on that. It just takes time to get it all done.
