Need free dash wiring diagram for a 1991 sonoma with a digital instrument panel

The plug that goes into the back of a regular sweep style instrument cluster is different than the wires that i9s present on the wiring plug that is correct for a digital instrument panel. I have the digital instrument panel with the plug that is required to install it but need to know what the functions of the dash wiring are and the lay out of the wiring plug that goes to the digital instrument cluster.

SOURCE: 1991 Volvo 740GL Speedometer

I remove two panel underneath the steering column. The first panel is removed using a 10 mm socket. The second panel is removed using a torx socket (can't remember the size). Removing these two panels gives you room to get to the clip on speedomter. Looking at the speedometer, you should see two rectangular holes on each side of the speedometer cover. I use a awl to push in the clip (you could use a screwdriver). Looking underneath the dash, you should be able to see the clip you are pushing on with the awl. I take my 2nd awl and put it behind the clip. I get the left side to release. One the speedometer cover releases, you can see the speedometer. You will see the 4 torx screws (t20) and two smaller clips holding the speedometer. All that is left is the wiring. (I take a sharpie pen and mark one of my wire locations on the speedometer. I am not sure what it does. It is a single wire.)

What color is the sending unit wires that go into my cluster panel

fuel level sensor-undefined-undefined-0.jpg It doesn't work that way. The fuel level sensor is wired to the pcm. The pcm sends serial data to instrument cluster telling it what to do with fuel gage. The purple wire to fuel level sensor, is ref voltage--5 volts, goes hot with key on, The bottom black wire in diagram is ground. You can check voltage and ground. The gray wire going from pcm to instrument cluster, is serial data. You could use digital logic probe to see if activity on the circuit. The digital logic probe will have lights and make sounds to let you know there is activity on the circuit, but, you won't know what it means other than there is activity. If there is activity, I think something wrong with instrument cluster. That's all I know. good luck

I have an 01 Pontiac Azteca the problem is everytime I put the car in gear it shuts the dash lights and radio light off, any idea what could cause this?

A bad or lose ground ! Checking a wiring diagram would show if these thing's share a common ground . Transmission , instrument cluster lighting an the radio lights up with the instrument cluster . You can go onto youtube an check out videos on how to read a wiring diagram , how to do voltage drop testing , basic automotive electrical circuit testing . Then you could go to http://bbbind.com/free_tsb.html free wiring diagrams an test the instrument panel back lighting circuits ! You will need a DVOM - digital volt ohm meter an you will more then likely need to take parts of your instrument panel apart . Your probably better off taking your vehicle to a qualified repair shop .

REPLACING DOME LIGHT - DOES IT MATTER WHAT SIDE THE ORANGE WIRE GOES ON - OR THE WHITE WIRE AND AT WHAT ANGLE???

no it doesn't matter...the orange is +12vdc and the white is the "momentary" ground that is made with the opening of the doors , the switch, if one is up there, and the dome light switch on the dash instrument control.

My 1991 had the same problem...after many hours the hot red wire from the fused link on the firewall had voltage but it was lost at the 3 wire connecter behind the glove box (It must of got hot and melted and the connection was broken) the two green wires were also shorted out to each other...all I had to do was cut out the connector and reconnect the wires again and had my air back...hopes this helps...look for the 3 wire connector behind the glove box and disconnect battery and check for continuity.
