I am trying to hook up a relay to turn off a light when I turn on my
electric water, keep forgetting, I am sure this is a simple solution,
Basically my little "IDIOT" light will be on all the time when ignition
on until I turn on my switch for my fans and electric water pump on
vehicle, then idiot light will turn off. I know I could hook it up for
the switch and problem would be solved, but I have a temp sensor which
turns it off and cools down without ignition on. thanks
