i have an o2 plug that looks kinda like that...where is it on the wire harness?
what is it close to on the engine?
does it hang under the truck?
kinda looks like a maf or that other sensor on the back of the intake manifold.

Little more info on the whole 5.3L.
From a 2004 Tahoe with only 1400 miles.
The guy I purchased this 5.3L from bought it from a 4x4shop in Siloam Springs, AR.
I was told they reprogrammed the ECM, modified the wiring harness down to a 5 wire hookup.
List of those wires and what their for:
brown = Alt. light or gauge
pink = key hot (must maintain 12v while cranking)
green= battery (hot at all times)
white = tach
purple = starter
----------------------------------------------
I know it is not the MAF sensor.
It does have 4 wires.
left to right in picture
I beleive them to be:
orange, purple, brown, pink.
The drive by has been replaced for a cable throttle.
I would assume that when the harness was reworked that they would have removed the wiring for the drive by. But I know what assuming gets you.
it is the plug hanging to the bottom left in picture
(MAF is the one hanging bottom right)
up behind the starter, crank pos senser

oh yeah, O2 sensor, looks like you have a crank sensor wire already.
