i just got a autometer stoich (a/f) gauge. i was wondering if anybody else was running one and if they like it. also how did you hook it up and was it a pita to do.
Did one in December....I mounted it on the A-pillar, and I like it a lot. It is really just a light show though. It goes from green to red and back again all day.
It only had 3 wires: The first was red, which went to my ignition (On) wire
The second was black, which is ground,
And the third is purple, which goes to the sending wire off the O2s.
I tapped in to the sending wire right in front of my oil pan, where there is a harness to the left O2. I wasn't sure how to find the other one but there is a tread in here somewhere about the specific wire colors to tap into.
