Under the left side cover the plug that is dangling under the number 2 and 3 relays. I can't figure it out from the wiring diagram either. The image is from page 417 of the Service Manual. It does have power that is switched with the ignition. I am looking for a place to tie into for power for a com system. It would be handy if this would work. Anyone have any suggestions where to go for fused and switched power. Maybe one of the unused connectors under the fuel tank?
