Wideband Gauge Power Source?

[CarRacer]

I got a new toy in the mail today, an AEM wideband gauge.

I started to hook it up today and wanted to do it right. It recommends a 10A switched power source. I'm wondering where the best place to get that would be.

I plan on running the gauge under an aftermarket radio. A power source near there would be awesome. I'm thinking that running a wire from the fuse block near the battery may be best though.

Thanks for helping.

I ran the power for mine from the ecu power. I had tried it in another location first but it interfered with the radio.

Did you run an inline fuse?

Ignition switch. Get yourself a turbo timer harness and you won't even have to hack the wiring.

I tapped into the hazard switch. There is a power source there when the ignition is on.
