OK! That got me to the right section.
It shows up as the fan relay supply with a fusible link right at the starter.
Just be sure that there's still a fusible link there because there's no
other circuit protection in that line. No fuse, no nothing.
If the link gets cut out or replaced with regular wire,
it's a fire waiting to happen.

Glad ya found it!

WOW, thanks for that info.

Going to play it safe and get it properly fixed real soon.
Would hate to see my Volvo die in a fire, its lived a long life and deserves better.

I just for giggles took the wire loom cover apart and physically traced the wire. The"brown " pigtail is indeed the Fusible link spliced to the Bat + wire for the Cooling fan

Not true,

Some clarification for future readers.

1. The "Brown" wire was not Brown, it was RED!
The Aux Fan circuit runs on smaller wire than the big cables (that are attached to the starter solenoid lug).
See below:

2. Below is the photo from my 1998 S70 GLT. I labeled everything for future readers.
