I'm in the process of rewiring my 47 coupe. The circuit breakers are attached to the back of the guage cluster. The dash wiring harness diagram shows using in the older style breaker and resister set up. My resister is mounted on the firewall. Can someone tell me what the "B" terminal is on the older style breaker as well as the other two terminals ?

Most circuit breakers have a battery or buss side and a load side. The resistor can be connected either way since they generally no polarity associated with them.

Not sure this is of any help, but this is the 47 wires to the CB. The second one is a 51 CB. The third one is 47 CB and Gauge wiring.

B is Battery
H is Headlight (30 Amp CB)
A is Auxiliary (15 Amp CB)

The 48-49 Truck diagram may be more like what you are dealing with.
