Body Harness Connector

["Neil Shaw" <neil@xxxxxxxxxxxxxxxxxxxxx>]

I need a little help in solving an electrical problem on our '72 Javelin.
The interior lights go on when the passenger door is open but not when the
drivers side is open. Hence I figured the door jamb switch is bad. I took it
out and it appears to be fine, so I touched the wire from the switch (black
with tracer) to the body which should complete the circuit and turn the
lights on and nothing. So, I have no juice coming to this switch.
The manual shows this wire leading back to the "Body Harness Connector".
Where is this item mounted?
I suspect this is not the problem since the manual shows that the black with
tracer wire merges from both switches before reaching this connector, but I
want to check it out anyway.
Also, the manual shows a black wire coming off of only one of these switches
(but you can't tell which is left or right in the diagram). Without pulling
apart the other kick panel to see the wiring at the passenger switch, does
anyone know which switch gets the two wire lead? I find a stray black wire
on the drivers side, but the door switch does not have two plug-in's on it
to receive this extra wire, and grounding both does not turn on the lights.

Sorry this is so wordy. Hard to describe otherwise.
Thanks in advance for your help.
