I'm trying to install an o2 simulator purchased from www.o2simulator.com. I plan on splicing into the wiring in the ECU since I have a patch harness.

OK, now according to this ECU diagram (http://www.roadraceengineering.com/evo/tech/EVO-ecuwiring.htm), there seem to be three sources for 12V power: Pins 12 (switched), 25 (switched), and 80 (constant). I just wanted to confirm that "switched" means that the power for that pin is only "on" when the key is at the II position (ignition position) and that "constant" means that the power for that pin is "always on."

Thanks in advance.
