Looking for the easiest way to hook these gauges up.

Temp: Is the allen wrench slot next to the filler tube a good location? I was thinking about the TB line, but that requires some extra plumbing.

The fuel mix gauge -- I know it isn't that helpful, but I have one so might as well hook it up. If not to the ECU, then where is the easiest place to tap into the Oxygen sensor line?

Thanks for any help.

I guess you could t-tap the ECU line from the oxygen sensor next to the ECU but I wouldn't bother. Sell the gauge on eBay and buy some pizza and beer.
