Need help with heated 02 sensor

I am installing a casper electronics heated 02 sensor on my GTZ. Need some help.

Where is a good switched 12v power to feed the heated sensor? Instructions also specify I need a really good ground at 0v.

Here are some pics, wires are short so Im sure I will need to extend them.

Alright just for those who have Rons header.....this upgrade is a must!

I finally got the sensor installed and she runs and idles great!

I ran the power to fuse #8, which is hot only in run. This is the fuse for the heater by the way. As for the ground from the sensor I bolted it down to a bolt that once held the stock intake box. Tested with the meter and all was well.

Again this is a must if u have rons long tube header on ur quad.

You could do a write up.

Looks great, super-clean. I think Money pit is right, you seems to have the handle on this. After pics and even a parts source list/price list would add nicely for the Quad crowd (I'm not there yet, but I would love to convert my old '95 Z-26 into a Quad/5-speed car, if I take her back, which is looking more and more likely). A complete build from header installation on would be really informative.

I would also like to see tests showing that the heater element is actually necessary -I know those headers have the collector pretty far downstream, but are the exhaust gassesreally that much cooler twelve or eighteen inches away from conventional manifold placement? How much longer (under idle and under regular driving conditions) would it take a non-heated sensor to warm enough to switch to closed-loop mode? Does the sensor really have any loss of efficiency at that spacing in idle after it is warmed?

Don't get me wrong -for the little effort it takes to set this up right (from what you've posted), any benefit sounds worth the effort, I'm just wondering how much of a benefit you are getting... :good:

Just wanted to post this link for reference. Also helps with replacement 02 sensors if needed.
