I am rebuilding the wiring harness for the 95 E300D I recently acquired but ran into a mysterious wire set.

There is a set of wires that appear to go to a connector or something near the injection pump.

All I have are the wire ends and I cannot find the connector.

One of the wires go to one of the pins for the idle pot and the other goes to Pin 3 on connector x26/7. This is the main 14 pin connector behind the battery and is listed as "Engine harness connector (12 pole)" (yea, it's 14 pin not 12).

I have identified the 13 other pins but can not find pin 3 in any of the wiring diagrams.

I wonder if it is for the Cruise system but I can not seem to locate a connector on the CC box behind the IP (maybe it's just a vacuum amplifier or something).

Also, I do not see another wire coming off the ISC actuator in the wiring diagram.

I have looked through the A/C system diagram to see if it's something there to no avail.

Any ideas?
