Ignition On ONLY Hot Wire?
I'm putting in a heated oxygen sensor, can anyone tell me where an ignition on only hot wire is to connect to? It appears my test light took a crap on me.

Thanks Guys, before I saw nutz4C4’s reply I found another test light that worked. I found power at the connectors that used to go to the air pump I believe and used it. It’s a wimpy wire but seems to be working. I’ll probably relocate to one of the above options with a thicker wire. Thanks

Started it up this morning prior to moving the wire and had the same poor running condition I had before going to the heated O2. Code for O2 sensor was present before also with 33 for the MAF.
Service engine light came on again so I hooked up the scanner and 33 was still there but the O2 was not this time it only said O2 lean exhaust and MAF sensor or circuit to high. Switched the hot wire to the fan relay and disconnected the battery and turned the lights apparently they hold current? Tuner told me that one? After 5 minutes hooked it back up and all is normal again. Hopefully it will stay that way.
