oil Temp gauge Installation help

[Eclipsemblue]

Hey,
Im currently installing my oil temp gauge on my 420a and i have a question to ask, this applies to mostly any gauge, i have to setup a wire to the ignition switch so it knows when to turn on, you should know what i mean if you have done this. My question is what wire do i exactly wire it to, i have 5 gauges are they all gonna have to go to the same one ? pictures would be GREAATTLLYY appreciated Thanks guys

There is no specific wire. All it should need is a 12V switchable source. All you have to do is get in there with a test light and poke and prod to find one. Splice it in and you should be fine.
