Lubricant for wiring harness ?
I had a devil of a time removing the 3 wire pig tail from the alternator and I don't want to go through that ever again. Is there a lubricant that I can spay on a wiring harness that will assist in removing it from its nearly frozen on position ? Maybe something I can spray on ahead of time so it has time to penetrate before I attempt to remove it ?

Deoxit is a good product too. It cleans terminals and leaves a lubricant behind. I’ve never tried it specifically to “break loose” connectors but it may help.

I was thinking in terms of some sort of spray that would seep into the wiring harness which would , hopefully make it easier to pull out.

I think all the underhood road grime is what makes it difficult. Mine was the same way.

I've always just used plain old WD40 on my wiring harnesses and stuck on vacuum hoses. This cleans crap out well, makes them slippery enough to pull off easily, and is non-conductive. It probably leaves enough residue that it just collects dust and recreates the problem the next time I need to get to them, but then I just spray them down again.
Anything that is permanently lubricating will collect dust if it's open to the elements and just turn into a grimy crud trap, so you just needs something to cut through it.

DeOxit spray. Specifically for electrics. Let it soak, work the connector in and out, then blow out any excess before any sparking/arcing might occur. Good for stiff household electric plugs/sockets. It must be good because it costs a lot.

Dielectric grease is good for protecting connections from oxidation an keeping them lubricated so they will come apart, but it does not conduct electricity so should not be applied directly to contacts. Terminal grease, like in the old Ford light sockets is conductive. I started using Fluid Film in the early 90's while working on a commercial fishing boat, you used to have to order it through the mail from a distributor back then. I use it on everything.

You should never use a conductive grease in a connector. At least not any connector that is more than a basic 2 wire connector which does nothing but provide power (Even then I would be very wary of doing so). Otherwise it's a great way to create all sorts of problems. If you use conductive grease, you are essentially connecting all of the wires which run into that connector. Imagine what that would do to a sensor connector for instance which now instead of seeing a changing voltage based on what is happening with the sensor simply sees a constant voltage because you have connected the power feed back to the wire sending a signal back to the ECU.
