Need help identifying a part
On top of the tranny where the clutch slave is bolted, there is a black wire that is grounded there. The wire goes into a tiny black box thingy (soldered on?) and then comes out the other side and connects to a connecter.
What is this, what does it do, and does anyone have a part number for it? The wire broke off the box so I need to find a new one, but I can't find anything on it in the FSM.

ITs basically a ground with a capacitor on it. I believe its there to help filter noise, but I could be wrong.
Your best bet on acquiring one is going to a junkyard, or Rotary Resurrection. And you CAN run without it. popular consensus is that it causes erroneous oil pressure readings, but I never saw a difference with or without it.

Cool, I'll check RR and see if they've got one. Kinda funny that you mentioned the oil pressure misreadings, my oil pressure gauge pegs itself at the top whenever the car is on. I think that might be another problem though, I have the wire grounded with no little box currently so it may or may not be that.

Yes, it's a damping capacitor for the oil pressure sensor. You're not supposed to just ground it - it's giving you the problems you describe. There's an identical capactitor mounted on your driver's side shock tower - this is for the toggle switching of your trailing coils. You can theoretically "steal" that one for the oil pressure one, as they are identical.

Took it to a mazda dealership they showed me the parts fiche with it there, couldn't say exactly which one it's from. I'm sure its in the FSM tho.

Um, I dunno what you're trying to say, but the oil pressure sensor pulses enough to be a problem with readings. This grounding cap keeps the pulsing down so your oil pressure gauge doesn't flicker with these pulses.

It's not connected to the stereo in any way, so I have difficulty believeing what you've been told. It is connected to the oil pressure sender circuit, so Ted's answer makes a lot more sense.
