Can't seem to find any straight answers on how to route the gauge. I am mounting it on my steering wheel. What wires do I use to power it and where do I route the wires for the o2 sensor? How do I get it underneath the car? Can I do it thru the shifter underneath the center console? Thanks for any suggestions. I suck at wiring things without step by step instructions. Help please! :)

Someone's gotta know how to do this...

easiest way to get a wire through the firewall into the cabin from the engine bay is the grommet for the main wiring harness. Theres plenty of extra room. Cut a slit in the grommet and push your wires through. Unfortunately, I'm not at all familiar with sensors so i can't tell you how to hook things up

Pm coming

thanks, I appreciate it!
