So I was wiring up an electric fan and I ran a wire to the blue wire on the back ofthe ignition that I thought was ACC,So when I turn the key to on the fan runs and when the key is off the fan shuts off but I noticed my rpms drop slightly when I hook it up and also the fuel pump seems to take longer to prime,Is the blue wire behind the ignition ok to use for this?Seems like the fan is taking alot of load,Maybe I should run it else wear?Let me know if this is normal I dont wanna run lean because my fuel pump is getting the juice it needs.Do I need a relay to prevent this?
