Wiring question

[AutoEuphoria]

I currently have my ProSport mechanical boost gauge wired to the F43 fuse (cigarette lighter) via a fuse tap. I chose that fuse because it is powered only when the ignition is on, which is what I needed/wanted for a gauge.

I recently bought a methanol injection kit. I am trying to figure out how to wire the controller and pump for power. I was wondering if I could tap into this same fuse, or if that is too much coming from one fuse spot? If it is too much, any suggestions on which fuse I could tap into for power for the pump and the progressive controller? I was hoping to wire it so that it would only be active when the ignition was on. I was worried that if I wired it to a direct power source (like the door lock fuse or to the battery itself) it might draw power constantly, draining the battery or doing damage to the unit.

Any input would really be appreciated.

cigarette lighter has a 15Amp fuse. If your install, plus other devices plugged into the cigarette lighter, won't use more than 15 amps, you should be safe.

I would add a safety margin, maybe assume a max of 10 amps.

Alternatively, use the cigarette lighter to power a relay box somewhere and connect your kit to the main battery. That way it will only turn on when the car is on. This is similar to how some aftermarket driving/fog lights wire up.

Well, that makes sense I guess.

I wrote the manufacturer...hopefully they can tell me whether or not I can wire directly to the battery or a constant source, because that would really make things simpler. I just don't want it to be a constant pull/drain on the battery. Not sure how it works in that regard.
