Picked up a wagon last Friday.
Still going through and fixing some things.
Check engine light was on, turned out right o2 sensor was simply unplugged.
#3 fuse for AIR blown in underhood fuse/relay block.
Replaced the fuse, and it blew again.
Appears the smog pump is toast, unplugging it and the fuse doesn't blow.
Any way to test the air pump, or does this confirm it's toast...car has 140k.
Coolant temp gauge doesn't work, sending unit wire is MIA, all attempts to locate it have failed.
However I did find a mystery wire while cleaning up some PO wiring under the hood.
Can anybody identify it? It's spliced to engine loom right under alternator.

It is the right color for coolant temp sending wire(DK green), but has no continuity with the wire under the dash.
