How to power aftermarket gauges??

[Fj80oregon]

95 Fzj80 US spec. Getting my turbo buttoned up and trying to wire my AEM gauges boost, water temp and Air Fuel Ratio. I purchased a blue sea box with 4 outlets. I need a 12v source that’s hot with ign and acc preferably. Not sure how others have done this and would like some input and ideas that have been successful. I have a EWD but wiring is not my strong point. Thanks in advance.

I pulled an ignition switched positive from under either the driver seat or center console. I used that to trigger a relay. The relay has an 8awg power wire from the battery and from the relay to the fuse box. This way you're not overloading your switch source. The wire I used to switch the relay wasn't plugged into anything.

If you are having trouble finding an ignition switched source of power use a test light or voltmeter and probe some empty plugs with power on. If you find a hot wire turn the ignition switch off. If it goes off turn the vehicle on and check for power again and that it doesn't shut off after a short time. White wire and white wire with a black stripe tends to always be ground wiring.

for IGN power the wiper motor is a good one to tap off
