Trigger wire to electric water pump relay
I've been using the fuel pump (20) fuse for the activation wire to the relay going to the electric water pump as instructed ! The problem with this is the fuel pump fuse is live all the time and drains the battery down after a few days (130 ma draw). The fuel injector banks R & L are only powered when ign. is on & I'm good with that but not sure if that's a sensitive Cricut?
Maybe it's better to get power from the interior fuse block?

Your fuel pump control wire which is power side switched to activate the relay coil draws very little current and the injectors when activated draw close to 1 amp…what issues are you having and what is a “sensitive circuit” ??…you really don’t want to be tapping off multiple circuits with the same fuse…who instructed you to use the fuel pump control wire ??…what are the current requirements for this setup ??
