12V source?
Does anyone know if/where a 12V source when the engine is running only? I'm aware of the IG1 wire and while the rx7 seems to have an IG2, it appears they are the same (active when thekey is turned). Im looking for a wire that is ONLY hot when the engine is running.
Anyone? I need the wire color/harness location. Thanks.

anyone?

I haven't verified it, but by the looks of the schematic I think the switched-side of the Circuit Opening Relay does what you want.
IGN ON = OFF
CRANK = +12V
RUN = +12V
Wire color is Blue/Red and routes to the Fuel Pump relay and the Fuel Pump Resistor. Be sure to use a relay rather than directly power your device from this line (especially if this is for a WI pump).

Look at the fuse panel near the dead-pedal. Just above the cover for the fuse panel you should see two unused (at least on my 93 R1) female spade sockets. I don't remember about the left one, but the one on the right is hot when the key is ON. All you need is a male spade connector.
Eh, never mind, I didn't notice at first, but it looks like you need it on the engine side. Can't delete for some reason. Sorry.

david, i think youre out of luck on that. . . in order for that to work. . . mazda would had to have made the ignition switch like this: off---acc---start---run. it is like this in stock form: off---acc---run---start. . . mazda would have no need for making a circuit like you request nor is it really possible (AFAIK). the key ALWAYS returns to RUN. so there for. . . anything that turns on when the engine is running will turn on (electrically) when the key is simply rotated to the RUN position on the switch.
i think youre either stuck with a manual operation switch or youll have to come up with some new circuit.
good luck,
paul
btw, what in the world do you need this for?

I'm working on something top secret, hehe.

i had the same idea with the a/c compressor. . . BUT the a/c compressor is operated by head pressure. its only on when the engine runs. . . right. . . that doesnt mean that the electrics dont go to it when the key is in the RUN position. . . notice, you can hit the a/c button on the dash and the led comes on.
top secret!!!!! just as long as it isnt a butt plug!!!!! hahahaha

BTW, anyone smart enough to be working on a top secret project should probably be capable of reading a wiring diagram and using a multimeter to find their own ******* wire...

ZeroBanger, just in case, don't overlook this:
It's 12+ only when the engine is running or cranking.
