Where do people get 5v from on an evo 9 to hook up some aem sensors? I've got 4 sensors hopefully they will be fine tapping from one source/pin? None of them are widebands.

 

If the sensors are the standard +5, Ground, Signal, then you can use the same 5v power source that drives your TPS, and you can use the same ground that drives your TPS. Then just run the signal wire back to where ever you need.

You can also use your MAP sensor to splice the wires in. You can also pull up the pinout and pull the +5 from the ecu pin directly and run all new wires.

I just did this on my Evo 8. I taped into the +5 and ground for my AEM Sensors so that I did not have to run the wires from my gauge to the sensor. I only needed to run back the signal wire.

 

Pin 23 looks good as well anyone use it? amp limit unknown. Nvm it's battery voltage. Stuck with tps instead.
