Key On 12v source
 

I have moved my battery to the passenger bin and added a 40amp 3-circuit fuse panel to power the EBC, wideband and cooling fan on my IC. Is there a preferred circuit/fuse to tap into to get an ignition on signal to power up the relay in the aftermarket panel? I am assuming I do not want this to power up with the radio on the first spot on the ignition. I am trying to avoid digging into any steering column harness or anything along those lines.

Thanks for any advice.

On the fuse box inside the car at the top there are open spades you can tap into

That's the one I use too. Just above the fuses on the right is the easy one on the main fuse box by your left foot on a USDM.

Awesome, thanks both, will check it out tonight.

So the open circuit between "Stop" and 'Sun Roof" is hot all the time. I ended up using one of those taps on the fuse for "Meter". Works good so far, its hot when the ignition is on position II.
