Yes, clean them with contact cleaner, and use some fresh dielectric grease on reassembly.
It's a cuss worthy job, to be sure; but it's amazing how many ECUs get turned in that nobody can find a problem with, but the actual problem is a bad contact. (Contacts are almost ALWAYS the first thing to give fits on electronics when they're not enviromentally strained or drowned.)

All the wires have been removed. Close to 60 of them. All terminals have been slightly squeezed. All are labeled so I know how they go back.
But here is a potential problem. About half of those puny little tabs that held the round terminal in the connector cavities have broken off. Have to say, it would be impossible not to break at least some of them. They are incredibly fragile. Soooooo, does this spell trouble for me when I go to plug the harness back into the PCM? Will the connectors get pushed back out when I plug the harness back into the ECM?

I was thinking the same thing. And I'd almost have to do each one, one at a time. If I tried putting all the wires back in the connector and then shoved in on I'd likely not see all the ones that get pushed out.

So you're saying the terminals wont be able to plug into the pins with that red retainer in the way?
I kinda gathered this as I went to put back two of the wires and they don't seem to sink in all the way. Didn't know if that was because I could not get enough oomph to push the terminal over the pin because all I have to grab on is the wire once the terminal is buried. I know the insulation was buried about 1/3 - 1/2 an inch into the connector when I was taking them out. Now I just get the terminal in and I can get it no further.
The two pins I pushed in from the back (with connector installed on the ECM) back out with no problem.
Can I buy a new connector somewhere?

Here's a picture of those tiny tabs that busted off. If there's a special tool that keeps someone from breaking those tabs I'd like to see it. Can hardly see them inside the connector. I'm not the most graceful person but I'm not a clod either. I was being very gentle but obviously not good enuf.

And finally...
I pulled the retainers out and re-plugged the connector into the ECM. The wires are going in much deeper...where they were before I pulled them. Nothing holding them in though. Feeling better.
The wife comes out and looks at my wad of wires that looks like the end of a mop and asks, "Who told you to do that?" I says, "Some guy on the internet." She says, "What could possibly go wrong?"
Ye of little faith.

Hee!
Well, that's what the depinner is for; it's supposed to barely fit over the outside and depress those tabs so you can pull the pin or socket out the back.
AFTER you remove the retainer, that is.
I hope this all works for you. If not, you might want to investigate a new connector, but before that, I'd toss in the towel on the PCM and replace it.
Again, my steps are through the more likely and cheapest to the less likely and most expensive.
