I just got a new Autometer A/G gauge, carbon fiber face to match the trim. But no instructions. There are three wires. Red goes to 12V+, black to 12V- or ground, and purple. Same color as the lead to the O2 sensor, so I asume I splice it into that. Just piggyback it, or what?

I know there are a few out there. Help me out!!

You need Allmachtige (works for Autometer, and runs one). He'* dealing with some family matters. I don't have a clue. Jeffrey is running one, too.

Yes that purple wire connects to the O2 sensor. You can splice it or but this clean looking kit that makes it plug and play? Pig Tail

92'* have a one wire non-heated O2 sensor. That pigtail won't work. Is there a one wire model?

Not that I'm aware of? Just stumbled into that one day...sorry.

That'* ok, I've done my fair share of wiring in the past. Anyone have an opinion of where I should get my 12V from?

Now If my pillar pod from DP would show up...

An easy 12v in the dash is the cig lighter. Also you could run from the fuse panel under the steering column.

Allmachtige and I were talking about these gauges. You're best bet is to hook it up to the car wiring, not the o2 sensor. So when you change sensors, it still works,
