gauge install?

[LilBrownCTD]

Hey there I'm hoping you all can help me out with this stupid question. I'm in the process of installing guages in my 2001 dodge Ram, now my perdicament is this, the tranny temp guage has this electronic box ok easy enough but it has wires that you need to plumb the Power and Supply wires, now according to the wiring diagram the supply wire should be hooked to the ignition, now this is where I get confused where can I hook this wire up to so I can go about using my gauges? Thanks for all your guys' help.

Use a meter or test light and find a fuse with power to both sides when the ignition is on then just tap into that and your good to go.
