What plug is this?
2004 5.3L Harness
http://im1.shutterfly.com/procserv/4...101AaMmTRm4cMY
i think it the coil pack plugif so u should have 2 .
I looked on my 06 but didnt see it. Seems like i remember that plug but dont remember what it goes to ill keep lookin tho lots of 5.3s around here.
How about a clue. Its got 4 wires? What colors? Maybe a throttle pedal connecter? where does it hook into the main harness? Coil pack has about 8 wires to it. Could be MAF sensor connector but I think those have 5 wires on the 2004.
boy what a stupid little test for us pros ha .lol
+1 Im pretty sure thats it too. Only plug with four wires and a lock like that. Mine is a little different buts its two years newer.Quote:

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)

ok...my guess is o2 sensor since it hangs down there
here is and o2 sensor for an 04 silvy with the 5.3

up behind the starter, crank pos senser
oh yeah, O2 sensor, looks like you have a crank sensor wire already.
