Most of the wire connections are with insulated connectors, and for the most part, don't have heat shrink on them because they are inside. I have got some wires held together as a bundle with tape, might wanna check those.
Didn't think so the parking brake cable, so I'll check that. I'm pretty sure it has to do something with the engine being on, as I was just out vaccuming it out with the radio on and no smell.
