i hooked mine up to directly to the driver's side o2 sensor. the purple wire to be exact. i used one of those wire taps to do it. works great. The power i tapped into the IGN port in teh fuse box. They sell fuse taps at radio shack which you can use for this.....and just ground the gauge somewhere under the dash. I spliced into an existing ground.
