Well, the 5V boards pull considerably more power than the 3V boards. That's both at idle and running. The 5V boards just run hot.
They are commanded from the lead unit. The coupler connection in the slave comes off pin-6 of the eight pin connector, and it comes across the 10-pin tether from the master.

Sorry, I meant which board component on the master PS-2 board actually triggers the F coupler? The trailing A unit slave board would have a similar device for the R coupler presumably.
