As Moto numbers them (with pin 1 being on top), it's pins 3 and 4 (3 is the hangup box lead, and 4 is ground). As ethernet numbers the pins, it's backwards from Moto and is 6 and 5. Years ago I saw a Maxtrac for sale at TRW that had a mess of Dymo labels on the speaker area of the front panel. A closer look revealed that someone had drilled a hole in the center of the speaker area, and mounted a mini-toggle switch. It was labeled "PL" and up was labeled "ON", center was "OFF" and down was "HANGUP BOX". No comment. Mike WA6ILQ
