According to the bentley, DF should be a black wire hooked to the DF
terminal at the regulator, and D+ at the generator should be a red/
black wire hooked to D+ at the regulator. In addition, D-, the smaller
brown wire needs to be hooked to regulator ground. There may also be
another smaller lead present at either end of the D+ lead for the
diagnostic connector on the firewall. It looks like Pin 6 and Pin 14
of the diag connector are hooked to the D+ lead.

If your wiring has been replaced with a non-standard color and you are
not certain that it is wired correctly, I would suggest first pulling
the battery out of the circuit, then disconnect both ends of D+ and DF
(i.e. pull the leads off at the regulator and the generator), and then
ground ONE side, either D+ or DF inside the car and then use your
meter to see which wire has continuity to ground at the end of the
wires in the engine bay. At least that way you will know for certain
which wire is going where, and that the wire is intact.

As for 'will hooking the wires up backwards cause my symptoms', I do
not know. Could be backwards, could be a broken wire for all we
know....

Good luck with it.
