Are you sure you don't want to do a harness replacement?

That's what I was debating. What are your suggestions?

You are miss wired to the starter solenoid.

He will have a harness:
The starter solenoid doesn't explain the blower though. That is the ignition switch.

Huh? I replaced it this summer and I thought I put it back how it was supposed to be but there was a lot of bsing flying around so I very well could have screwed it up. Too cold to investigate but I ran out and snapped some pics.

I have a relay, but the solenoid is mounted on the starter itself.

The fusible link is 18 gauge/green per my FSM. I assume the other end is supposed to be on the relay with a 3/8" looper like all the other 4 or so ones?

Yep, where were the wires you replaced? What circuit was it? The blower is switched ignition so the issue must be with the ignition circuit.

The yellow wire going down to my starter that joins into two across into the bulkhead connector and another that goes under neath the dash through that harness eventually reaching the ECU. Luckily I pulled the ECU and there appears to be no damage there. There are some wires that melted from the heat of the yellow ones and are conjoined and I assume they are the ignition switch and blower. Just picked up another fuse link. No one in town had any green ones so I picked up a blue one but it is 18 gauge so should I tag it with something or mark it for future reference?

I still dont get how that harness cooked without taking out a fuse or a fuseable link. Contrary to belief the whole point on a fuse is to protect the wiring not the electronics and yours definitely failed. You have me concerned because I am setup the same way as you with the 2.5L. I have a fuse box to replace the fuseable links ready to install, but the way yours fail would mean that something else needs to be changed to be protected. Here is a link to the pdf so you can search the wire colors to figure out the circuits. It might help speed things up on your repair. That yellow wire goes everywhere!
