Are you running an XFC? Please help!

[m.o.b.s.]

I'll mail 2 cookies to anyone running an XFC that can layout which wires they've tapped or intercepted.

Pre-cat in (gray/lt. green)/out (pink/black) intercept?
Post-cat in (gray/lt. blue)/out (pink/red) intercept?
MAF In 1(gray/pink)/Out 1(pink/lt. green) intercept?
MAF Out 2 (pink/blue) tap to factory wideband/pre-cat sensor?

Also, please specify the year, engine size, PZEV or not, and if you have any CELs. I'm going crazy.

I have an '08 Mazda3 2.3 Automatic

Let's make this simpler. How about just the pink wire with the blue stripe? What's that tapped into? Do you have a CEL? 06+ Non-Cali cars with 2.3 only please.

I'm asking because I've been told 3 different things from the same person on how to connect the XFC to the 5-wire sensor. My ECU is starting to look like a little butt connector habi-trail for tiny little hamsters.
