So, basically, I just finished my Mark VIII swap. The motor runs as long as it is hooked to a battery charger.

On the instrument cluster, all the indicators that worked before work now, except the theft light. It doens't turn on at all any more but the engine still runs (thinking bulb)

The ignition works, the gauges work (not oil pressure, but thats more than likely due to sending unit)

None of the interior items work though. No door chimes, no interior lights, no exterior lights(heads or tails or turns), no radio, AC compressor will not turn on (maybe vacuum issue) however the vents blow air, and no power locks (power windows do work)

The motor holds a nice 700-800 RMP idle, revs easy.
