So now, your truck runs great but you don't have a speedo, water temp, oil pressure, and fuel level. Correct?

Let's stop for a minute and check the basics. Were they working before you replaced the Bosch VP44?

Have you checked all the fuses inside the truck and under the hood?

Do the gauges swing to one side and then back?

Also, try running THIS.

That is correct. No it didnt work before the vp issue. I was in the process of trying to fix it when my vp took a crap. I did the instrument panel test and all the gauges do what they are supposed to do during the test. When going down the road all the needles are to the left as if the truck is off

You might need a PCM, not ECM. This is the one on the passenger side firewall near the airbox, I think. Check the connections there.

A little tidbit about the CCD Network. What you got is a room full of people and everyone's all talking at the same time. (PCM, ECM, ABS, AirBag, Central Timer, etc.) Each device is trained to listen for particular conversations (data) and process the data when heard.

So here is what you got...

Oil Pressure -> ECM -> CCD -> Instrument Cluster
Coolant Temp

Fuel Sender -> PCM -> CCD -> Instrument Cluster
Battery Volts

So instead of the older 94-98 style where the wires went directly to the gauges. The CCD simplifies the wiring down to 2 wires going to the instrument cluster. But I will admit it makes it harder to diagnose.

CCD Network

Ive gotten a few wiring diagrams from you and i believe this is one of them. I just cant find any wires that look broke or out of place. Everything looks like it should. Not all the colors match up but i dont see that being an issue. I just cant for the life of me find the problem and neither can anyone that looks at it. Its puzzling......I almost need someone with a running truck to pull off 1 plug at a time from the ECM and pCM until they have the same issue so i know which box it is thats bad because i think thats what it is personally

Let go backwards at it. What happen if you do a cluster test?

Ok. So that means there is a CCD network problem interfering with the communications. So if you probe the OBDII port there should be 2.49 and 2.51 volts to reference of ground.

So, which two pins in the OBD II are the bus positive and negative?
