heated vs non heated O2 sensor with headers

[Frank Enstein]

They can draw 10 amps so just make sure the circuit chosen can handle it. I relay is a great idea maybe with it's own circuit breaker.

So basically any wire that is hot with the key in the run position would work just fine if the above mentioned wire could not be found.

Seems to be so.
Said output from PCM also feeds ignition (coil and other thing), crank and cam position sensors, EGR valve, MAF sensor, injectors (via a fuse), etc, etc. O2 sensor heating is just one more added to the list.

Haynes shows all the above being fed with pink coloured wires.

the pink colored wire I believe is the 12V feed that feeds the tranny on Pin E. because if the O2 sensers short out it blows the transmission fuse. otherwise that's about all I can offer to this thread. haha

Here's the sensor I got.

xc_hide_links_from_guests_guests_error_hide_media

xc_hide_links_from_guests_guests_error_hide_media

is it compatible to 95 5.7 with 4l80e?
