This is the new style 1500 with a 5.3L.

 

I have searched forever on this site and Google. I think I've read every post for this truck known to man.

 

There are a few posts but seem contradictory and the one with a picture showing the tap under the driver side dash looks nothing like mine.

This one has a pic.

I tapped the green/white under the driver's dash. The D3 is showing standard mode. It shows a speed pulse growing slowly on the 3D menu but it is 0 in the diagnostic screen.

 

Am I hooked up right? This is the last piece to finalize.

 

 

 

Picture of mine attached. Tap in top right.

 

 

Thanks,

DARK GREEN/WHITE RADIO HARNESS

That sounds like more work :oops:

 

Are you saying I have to pull everything apart and grab that wire? I've never seen one posts suggesting it was there. Kinda makes sense. The stock radio had speed sensetivity.

 

I was really hoping there would one right were I currently have it hooked up.

 

Anybody else have an hopefully easier solution? :lol:

Let me get home and check the SI manual and I'll let you know if I can find the VSS for you, I am pretty sure that you won't find it at the radio though. Can't say for sure on anything as I am at work. I'll post tonight what I can find.

You can't find a VSS on any gmt800 or gmt900 series p/u or sport utility that has the VSS at the radio harness. This is all controled by the class 2 signal. You should be able to find the wire at the ecm, it is green and white in the pin locations as shown on those pictures. Not sure why yours is different as all the new body styles are the same wiring IE regular cab, extended cab and crew cab.

Wow...I don't read well.

 

That picture in the 2nd link on my original posts. That is right.

 

My picture was the front of the same box. It's a bit tight (wrapped wires /up under dash) but I just slowly flipped it around and lo and behold it is right there.

 

Tapped the green/white. Getting pulse now. Should be good to go.

 

I can't believe how long I spent on this and the answer was right there the whole time.
