quick question about ewp wiring! I have my meziere in the car from long ago and I had it wired it to the inginiton fuse so when the key is on the ignition the pump will kick. Now I got me this small lighweight battery (duralast etx16) from autozone and I dont like the idea of having my car with the key on and the pump drawing power. I want to have it on while the engine is running. which fuse or wire pf the fuse box I can utilize?

The air pump shuts off after a few minutes of running. Is it possible to change when the PCM triggers it in the .bin? Don't recall seeing anything but I'm not sure if the free software I use (tunerpro) goes that in-depth.
I used the AIR pump relay but wired ON as the trigger which is what you already have. When I need to load a tune or keep it in the ON position for a prolonged period of time I just pull the relay from the fuse box.
Maybe use the fuel pump instead? The EWP would only run when it primes and with the engine running.
