The receiver works on the outer most two contacts of the PF cable, and the
"legacy 9v" run on the inner most two wires.
Basically, outer wires for the power bus for controllers, and inner two
wires for load items such as lights and batteries.

Calling all EE's, robotics nuts, technic gurus, PF fanatics, and electronics geniuses... So by using the PF to 9V connector wire, I can run a PF motor using the 9V Train regulator. This is all wonderful...until I try to put an IR receiver between (...) (18 years ago, 25-Feb-09, to lugnet.technic, lugnet.trains, lugnet.robotics)
