Hello,
I’m in the process of adding two Spartan 2 O2 sensors to my carbureted flat 6 engine. One for each bank. I have a couple of questions.
-
I’m wiring power to the O2 sensors directly from a keyed 12v source. I’m wondering if the sensors will be damaged if I leave the key in the ACC posiiton without actually starting the car? Or does the heater internal to the O2 sensor shut off when it reaches a certain temperature? I’m curious if I should add a dash switch to disconnect power to the sensors in case I want to leave the ignition in ACC position.
-
If I were to run separate 12v feeder lines from the fuse panel to each sensor, what gauge wire should I use? Alternately, if I was to run 1 wire from the fuse panel and then branch off this feeder line to each O2 sensor. What gauge wire should I use for the feeder line in this scenario?
-
Lastly, what are you guys using for the LED light that is supposed to let you know whether or not the O2 sensor is running at the right temperature. I didn’t see an LED in the package I received.
Thanks,
Rich
