There's one of two harnesses under the air diverter in the drive-bay area...
The old ones have press-to-fit contacts and the body of the connectors are
made from an amber resin. The newer ones are crimp-ons and are in a white
nylon-like shell. The older ones can't take the current the uVAX draws,
and begin to oxidize. Oxidation causes resistance which causes heat...

You _will_ want to replace that harness if it's the older type. It's a
fire hazard. This goes for _all_ BA-23 cabs, BTW, not just uVAX-Is.
Those are just the right era, thus, a concern.
