All the gauges will work ( except mileage and range ) using the original engine sensors.

Mostly rewiring
You need to make the fuel pump relay run off the key ; a wire from the Ign switch
or better ;you can install a push button to the relay ( for prime after sitting longtime ) and keep - rewire the factory OP switch that runs the fuel pump
Engine will fire with the fuel in carb bowl and as soon as OP goes over 4 psi ( cranking ) the pump will run to fill the carb.
As soon as the engine stops, the pump will also stop so no need to remember to turn anything off

You need a thermo switch ( something like http://www.racerpartswholesale.com/product/2138/SPAL_Fan_Accessories2 )
wired to the fan relay to run the fan.
Remove ECM completely

Install a TBI low pressure fuel pump in place of the Hi pressure TPI pump and a non bypass reg at the carb
or keep the original pump and install a bypass reg in the engine bay using the stock return line to drop the pressure down
