Success!!!! Broken fusible link. There are 4 wires that come from my negative battery cable. 3 thin wires and one thick one. The thick one goes down to the area below the engine. A thin one is grounded on the right fender alongside the solenoid. Then a pair go into a fusible link? that go into a wire loom. I started moving wires around checking for the CEL to illuminate. When I moved the fusible link....Voila. I cut the link out and connected the wires directly to test. Fired right up. The question know is what gauge fuse do I use to link

There's standards for what gauge wire it is. Google should tell you, I'd prob add 5~10 amps to what google says

And congrats!!

Fusible links are often color coded to indicate amperage

You shouldn't need a fuse on a ground wire. But it doesn't hurt to put one on if it helps ya sleep at night

Computer's been off for a few days, so I didn't see the last messages. The ground (negative) wire also carries starter current in almost every automotive application so unless you want to purchase and install a 600+ amp fuse you probably don't want to fuse the negative side. Some boats do have separate (isolated) starter wiring, generally using 3/0 or 4/0 cables, but I've never seen it elsewhere. If someone has seen a fuse in the negative battery cable, please let me know - I'd be very interested in where it was done.

The reason I ask is because the connector from the pcm ground to the negative battery cable is bad. Wanted to know if it was safe to cut the connector out and just splice the wires together.

L.A.X. How do you mean 'bad'? Is it corroded, insulation falling off (such as being hot) by the connector, or ? Did you mean 'connection between the pcm ground to the negative battery cable' ? I'm not trying to be difficult, but the answer could be different depending on how and why the ground connection is bad.
If you just have a bad (broken, etc.) connector, there should be no problem in cutting the connector out and splicing the wires. All you would be doing is bypassing it. You could also install a spade or bullet type connector if you think you would ever need to disconnect that wire. That's what I intend to do when I get time to repair the 4X4 shift motor on my wife's '92 XLT.

I cut and spliced the wires. All is good
