Gauge cluster wiring schematic???
 

Anybody have one or a link to one? 2003-2007 classic silverado. Thanks

PM me if you need something better...:cheers:btw those are for my 06 crew cab

WOW! That's probably really great info for someone who knows how to read those things lol. I'm just looking for what each wire does...Mainly looking for:

bright lite indicator
turn signals (left and right)
speedometer
service engine light

and fuel level

High beam indicator, and fuel level signal come off of the serial data bus. These are not hard wired functions.
VSS dk gn/wht term A4 at IPC
MIL bn/wht

Has to be some way to get a reading for the fuel level right? Maybe off the wiring harness on the tank?

So you would want the pinout of the I/P connector?

Perhaps? I'm not real good with my wording. You all should just know what I mean lol

I would like to know what wires do what on the plug that plugs into the back of of the cluster

The fuel level signal is processed by the pcm it sends 5 volts to the sender and gets a level reading in return. This is information is processed by the pcm then sent to the instrument cluster via serial data over the data bus there is not a hard wired fuel gauge input. What kind of vehicle is this in are you converting something or is it all in a stock application.

It's on my truck. 2007 classic chevy silverado. Installing aftermarket fuel level gauge.

How bout this? Couldn't I get the signal from the wire directly off wiring on the tank?
