The culprit. Sniffed that solder point, definitely what I was smelling last night.
I have to cut into the black wire w/white stripe to splice in an additional wire due to my swap, previously it was soldered into it, but I've never soldered and need the car for work tomorrow I'm just going to strip more off the additional wire and wrap it around the ignition wire a few times and use electrical tape. It's on the harness plug end that goes into the back of the fuse box, so that will make it easier to clean up later if I find a connector or something.
