which wire goes to the oil pressure switch?

OH that makes sense too b/c I dont have one... So where the heck does the oil pressure switch wire come from? I cant find it!

Here are a couple pics of mine just to use a reference.

damnnnnn dude presuure wash your engine...lol

I'm scared to, I'm worried something might stop working or a leak will appear!!!!!!

haha wow thanks for the pics. I have that same wire coming out but it looks to be plugged into the alternator on the single wire area... i thought that was a choke wire or something. so if that goes there, i'll have to find the wire that goes to the choke/alternator area...

OMG I think we totally just made sense of this madness... I posted up trying to find out where this other wire went. I explained that it was on the back of the carb and looked like an EGR, well I looked on the diagrams section and it is the choke (haha my first mazda). So that yellow/red wire goes to the alternator (makes sense) and the wire that is currently plugged into the alternator is the oil pressure wire. DUH! I'm going to have all my wires in order yet!

I think the choke wire that comes from the alternator is a yellow with blue.

dont know but I now know for sure that is the choke, and i've read from everyone in here that the choke wire goes to the alternator. i pulled the wire completely and followed it so i could be sure....
