I know a lot of people have many electrical accessories such as electric fans, waterpumps, tachs, aftermarket radios, lights etc. I was wondering how people wire all of these accessories that require 12 volts. I dont want to keep taping the ignition switch for 12 volts because I dont want to overload anything.I seen a lot of people use multiple relays but I still dont understand how to do this. Does anyone have a wiring diagram? Any thoughts are appreciated. Thanks.
