David,
There is no "Accessory" circuit in our cars, but there is a way to get a 
switched power circuit.  What I did was tap into one of the switched circuits 
coming out of the ignition switch.  On the '78 that would be the BR/R wire 
going to the safety belt warning relay or the BK/Y wire going to the load 
reduction relay and the light switch.  There is another wire, BK, coming off 
the switch but that feeds just about everything else in the car, so you 
probably don't want to put another load on that circuit.  If it's a high 
power application, I would just use the BR/R or BK/Y as a signal circuit to 
acitivate a relay to power your CD.
Check your Bentley, the ignition switch is device "D" on the schematic.
HTH and GL.
