the blue plug most of us use for timing light behind the driver headlight is 12v switched with ignition.

Depends on where you need it.

Like koto said, the little blue plug under the hood is a great spot for powering an EBC solenoid. In the dash, the cigarette lighter and radio are convenient places.

I'm going to use it to hard-wire my V1.

yeah, I have my WI off the 12v to the radio, and now I'll probably use the cig for the radar detector, and I'll use the blue plug for EBC when MS goes in.

Im running my LC1 off the same 12v that the MAF is on, planning to plug the EBC solenoid into the blue plug.

I use the plug for the power windows (which I don't have) under the center console. Powers all of my gauge lights. WBO2 is tapped off of ECU power.

Screw that i just run a fused hot wire straight from the battery and control it with a toggle switch solid state FTW. The radio antena circiut can also be used.

I have taped "12 Volt Switched" wires from the..... ignition switch. Works great. I also bought a thing called "add a circuit" from Autozone. It snaps in where a regular fuse would go, and has another fused wire coming out of it. I used that for my O2 Power and KnockSenseMS. I pulled the fuse from the wipers and used that so it's switched 12V. Easy to do and easily reversible plus I never cut the factory wiring.

The wipers would still function Magna.

Productive day I had! I installed my WB02, hardwired my Valentine, and illuminated my boost gauge! Sure was a bitch getting that AEM gauge to fit into a vent. Nothing a mitre saw, file, and zipties can't fix tho...

Add-a-circuits are awesome. I love them far more than vampire clips.

Solid wire from positive terminal to a relay with the switch wire being anything you feel like tapping in to. Then you don't have to worry about pulling too much power on a pre-existing line.

cheapest place for these ad-a-fuses? My local Napa store doesn't have any.

A link would be awesome.

Go to Google and type in "add a circuit". You'll get one or two results...
