Probably the only need for AC stems from the need for a 60 Hz (cycle) 
time base.  It will likely run on 12VDC if applied in the correct places,
but a "quick 'n dirty" would be a 555 timer to derive a 60 Hz signal
for the clock input (I'm assuming you have a schematic).

The 555 timer is truly the "dirty" way to do it-- but if its just for your car
then it might be accurate enuf for the job.  If you're prepared to do more
work, I'm sure that others can provide you with directions for a crystal
controlled time base.
