1/4 the cost of a new compressor

DKS15CH is the Zexel model number. Use DKS15CH to search for parts. You can find Santech parts for a lot less.
DKS15CH uses the same front seal as DKS13G & DKS15BH.

Read pages 1,6 & 16. Use the Vida 2014D Repack not the one you got off eBay.

The front are 23mm discard. The rears vary from 8mm to 10mm discard.

Get the VIN number.

Get the Diagnostic Trouble Codes (DTC). Codes from Vida-DiCE preferred.

There still hope for that transmission. P0748 does not translate to a 1998 S70. I think you OBD scanner has poor translations. Not uncommon for generic scanners. I suggest you get a ELM327 interface version 1.4 or higher (or a good quality clone) and scan it with 850 OBD-II . P0748 is a generic code...

Install Vdash and see if it will read the VIN through the DiCE unit you have.

As old as the car is, it is bound to have some air leaks which can be the source of the backfire. I suggest you smoke test the intake and exhaust system. Fix any leaks you find. Keep in mind a lot of .01s add up.

The unconnected cables most likely are options you do not have. Inspect them with a Loupe for scratches on the metal contacts.
Scratches = been used before. No scratches = never been used.

Long time since I looked at this, but if I recall there were several things on the same circuit. I can't recall but I think there were 3 things. The barometric sensor, the (can't recall the name) sensor on the front cross member and I thin the 3rd was some sensor on the A/C system near the bulkhead...
