Yes it looks like that. Like you say, plug is black and the two wires are purple and Pink. Pink wire is a little bigger diameter than the purple. (He sent me a picture). Harness is from M&H and he states he has not been able to get anyone there to contact him. I really thought it was for the directional flasher but my OEM has two pinks and a purple....
Looks like nuetral safety switch for an automatic car; but I would expect both wires to be purple.
Do you have two wires going to a two prong parallel plug (instead of at a 90 degree angle) that are both purple with white stripe?
Four speed used the parallel plug to a switch on the clutch pedal. Mine is bypassed, as are many others.
Auto uses one like your show; but like I said, both wires should be purple uf that is what it is. Looks like 12 gauge wire. Not much else under the dash that is that thick other than the red wire to the headlight switch.
I believe the directional signal flasher plugs into that connector. Trace the pink wire back to
see if it has a "Y" or "T" connector or some manner in which it's tied to the neutral safety switch.
M&H may not have followed the factory wiring exactly.
Al may be right. The AIM wiring diagram shows a 12 and a 20 pink wire going to the same terminal and a purple wire on the other terminal. They may have just combined the two pink wires somewhere else in the harness instead of using that terminal as the junction.
Trying to help, I googled M&H wiring and got onto their site and they say in a FAQ section that they do not respond to e-mails but to call and then they also state they do not supply schematics except in some specialized wiring.
They also had this about us questioning the amount of wires on a plug you have and how it might be different than it was originally:
The harness I received appears to be different than my original?
Everything should match your original harness perfectly. Please keep in mind that all harnesses are built using the most current GM revision. From time to time you may notice slight differences from your original harnesses. These differences normally do not affect fit or function.

I have been doing car audio installations for years and like I stated before maybe see if you have power and do some continuity checks. I've had through the years chopped off radio harness ends and then have to figure out what wires go to what speakers, which wires are power at different key positions, and what is a ground.
