[DeTomaso] Early Pantera Wiring question

[Doug Braun]

On a very early pushbutton Pantera I'm working on for a friend, I've made
sense of all the connections to the engine and firewall electricals except
for two.  There are two black colored wires that appear to be original
because they enter the wire harness in an unmolested fashion.  Both are the
same gauge (12 or 12 AWG) and they enter the harness at the same point (just
above the alternator), but head off into the harness in opposite directions.
Only about 6" of each remains sticking out of the harness but their ends
they are connected together along with non-stock section of wire that went
somewhere before but the owner doesn't remember where.  I'm  assuming
they're a ground of some kind but I can't find where they head off to and a
continuity check shows they're not currently connected to the frame
somewhere.  I checked to see if one of them becomes the black wire on the
fuel sender but no connection measured on the Ohm-meter.  Can anyone shed
some light on this?
