Re: on wiring diagram
The ACC (accessory or ignition) is for the red wire which is 12 volts only when the key is on or in the accessory position
The BU (back up) is for the yellow wire that get 12 volts all the time, even with the car turned off. It keeps the memory for the clock and preset radio stations.
P. CON (power continue) is a 12 volt output for turing on your power antenna or to turn on an external amplifier.
SP. OUT (speaker output) you have 8 of these all color coded. The white and grey are the front speakers with the solid color being the positive and the black stripe is the negative The green and purple are for the rear speakers with the solids being the positive and the black stripe being negative.

Each component should be
labelled clearly on your diagram. Look at figure 6-A. The symbols used to
represent each component are pretty universal. Wire colors are abbreviated and
shown next to each wire. For example, Y means a yellow wire, V means Violet,
R means red, LBU means light blue. Black is usually abbreviated BK, blue is
usually BU. GR or GN are green, GY is gray. A wire color with a dash or a
slash means --- with a --- stripe. For example BU-W means Blue with a white
stripe, T/R means tan with a red stripe.

I think I have it figured out. First, the Haynes manual shows the lighter and radio circuit. The Chilton(sp?) does not.
The Radio and Lighter are both on a 10 amp W/Bu wire. My 91 Civic actually had a connector tucked behind the radio. A trip to your local junk yard may be helpful. The connector is a 4 pin connector, but only 2 are used.
The manual says the hot wire is W/Bu but the wire looked more W/Grn to me. I also was unable to find any reference to a W/Grn wire in the manual.
The commonality of the wire in the diagram showed as a 4 in a triangle, it was very easy to overlook.
When I found the lighter at the junkyard I also grabbed the portion past the connector. That's how I was able to locate the connector behind the radio. The connector an wires matched. I checked for current with a meter and it looked good. However, it's only hot when the accessories are on.
So far so good. No magic blue smoke has escaped. If anyone sees an obvious error in my posting, please let me know.
