I need a good source of switched power, preferrably near the passenger footwell area that is switched AND WONT DIE when cranking the car. Thanks!

That particular wire feeds off of an accessory fuse which loses power temporarily when the key is turned to start, thus he needs to tap into a wire which is powered by one of the IG1 fuses.

Sorry about that for I used an S4 wiring diagram not realizing your's is an S5. So the non ground wire doesn't have voltage w/key to on? I'll take a look at the S5 diagram but it takes a while to fully download unlike the S4 version.

EDIT: If your car is wired for power windows then the Black/Red would work.

Image below shows where connector G-10 is to be found. This connector mates two plugs. The front side of the harness has the following wires; R/Y, L, B, G/R, B/R, B/Y, L/O, L/Y and the other side of the connector has; L/W, B, L, R/Y, L/Y, L/O, Y, Y/L. B/Y in the front harness will work and this wire mates up with Yellow on the other side of the connector.

Being run off the ACC fuses the only difference between those and the IG1 fuses are that when you turn the key to start the ACC fuses lose power but only for a very short period of time. I'm not familiar with what a wideband heater is but all you need to ask yourself is if it's fine for it to lose power for the briefest of moments when the key is turned to start then you are okay.
