best place to pick up switched power under the dash
 

I'm not used to the whole relay under the hood deal and it was getting late so when I started looking. the car has a much of stuff hooked so I can splice in im sure but I would rather take it from stock location with out cutting any more wires.

I use the "add a fuse" from the local autoparts store, works every time.

This. I've never had any issues using them on my miata ... I think I've got 3 of them stuck in there now.

I want the power under the dash

there's a fuse box under the dash...add a fuse to the "engine" fuse.

Ha I remembered this after I posted, I was was tired, fighting with a seat install and it was late. thanks will do.

Not "under the dash" but I piggy on the connector for the cig lighter for e.g. WB.

that is a good idea. I way running out of time so I think I will use the add a fuse for now. I was hoping for a screw terminal somewhere but guess these cars dont have that. makes a clean install easy, thanks AUDI ;)

Add a fuse is baller as fukk!!!

+1 to add a fuse. Used them many times with no issues.

Make sure to find a fuse that's hot whilst cranking to power the wideband.

BTW what we are talking about is actually called "Add-A-Circuit" (made by Littelfuse) and looks like this

I'd say that depends on the WB.
Some don't like low voltage (10V or so) and are better served with power that's off while cranking.
I had problems with my LC1, loosing settings etc, before choosing a run only (like the lighter).

Good to know. I had an old firmware version that would "Schiavo-out) when I hot started the car and it would sit at 15.0:1 until I power cycled without using the starter (coast and pop the clutch).

it doesnt even matter where I put mine. when i crank i go below 10v, and the lc-1 craps out at around 11.3v or so.
