I have a 2010 Chevy impala LS instrument cluster and it has a 20 pin plug I'm trying to figure out which wire's on the back of the cluster are for the speed sensor, rpm, gas, and temp wires.


Boy your way off base . All the gauges are inputs from the ECM - engine computer . The VSS - vehicle speed sensor , ETC - engine coolant temp sensor , sending unit in the fuel tank , All this sensors input the engine computer . The PCM then sends this info on the GMLAN serial data bus ,communications network . The Instrument cluster has a microprocessor inside that translates this info an controls the gauges. You probably have an instrument cluster problem or a communication network problem . Your best bet is to take your vehicle to the dealer or some other qualified repair shop. Need to have it checked for DTC'S - diagnostic trouble codes.
Indicators and Warning Messages
Refer to Indicator/Warning Message Description and Operation.
Engine Coolant Temperature Gage
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine coolant temperature. The IPC receives the coolant temperature information via serial data message from the body control module (BCM). The engine coolant temperature gage defaults to 60?°C (140?°F) or below if:
?€¢
The ECM detects a malfunction in the engine coolant temperature sensor circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the BCM.
Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the fuel level percent. The body control module (BCM) sends the fuel level information from the ECM to the IPC via a serial data message indicating the fuel level percent. The fuel gage defaults to empty if:
?€¢
The ECM detects a malfunction in the fuel level sensor circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the BCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates in the IPC.
Odometer
The vehicle odometer is calculated and stored electronically in the instrument panel cluster (IPC). The IPC contains a season odometer and trip odometer A or B. Momentarily press the trip/fuel button in order to toggle between the season odometer and the trip odometer. Press the set/reset button for greater than 0.25 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC displays the vehicle mileage and trip mileage as determined by the engine control module (ECM). The IPC calculates the mileage based on the serial data vehicle speed information from the ECM. The odometer will display 'error' if an internal IPC memory failure is detected. The odometer displays either miles or kilometers and can be set through the customization menu in the driver information center (DIC).
PRNDL Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the gear position. The PRNDL display blanks if:
?€¢
The ECM detects a malfunction in the transmission range switch circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the body control module (BCM).
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed as determined by the engine control module (ECM). The IPC calculates the mileage based on serial data vehicle speed information from the ECM. The IPC receives vehicle speed information from the body control module (BCM) via a serial data message. The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of serial data communications with the ECM or BCM.
Tachometer
The instrument panel cluster (IPC) displays the engine speed as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine speed. The IPC receives the engine speed information from the body control module (BCM) via a serial data message. The tachometer will default to 0 RPM if:
?€¢
The ECM detects a malfunction in the engine speed sensor circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the BCM.

What would be the cause of sudden Intermittent engine overheat?


The gauge in the instrument cluster could be going bad ! maybe. Is that what your going by ? You need to have it hooked up to a scan tool ,not a code reader . It will tell what the ECT - engine coolant temperature sensor is reporting to the PCM - engine computer .The PCM turns on the cooling fans when the temp. reaches 262 degrees ! Are the cooling fans coming on ? Thermostat sticking ! Go to harbor freight an buy a Laser Temp Gun Infrared Thermometer , $30.00 . point it at the upper radiator hose an see what the actual temp is !
Engine Coolant Indicators
TEMP ?€¢
The instrument panel cluster (IPC) illuminates the TEMP indicator when the powertrain control module (PCM) determines that the coolant temperature is more than 128?°C (262?°F). The IPC receives a discrete input from the PCM requesting illumination.

?€¢
The IPC performs the display test at the start of each ignition cycle. The IPC illuminates the TEMP indicator.

Is the cooling system full of coolant ?
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine coolant temperature. The IPC receives the coolant temperature information via serial data message from the body control module (BCM). The engine coolant temperature gage defaults to 60?°C (140?°F) or below if:

2001 Chevy Silverado - 2500HD, 8.1L V8. Why did all except 2 gauges stop working?


I suggest you take it to a ASE certified repair shop , it sounds like you know nothing about automotive electrical systems . I don't know who told you that a hot wire is touching ! I'd say they don't have a clue either ! From my 30years experience , I'd say the instrument cluster is bad , because I know GM had a lot of problems with them ! But if you still think you want to mess with it , you'll need to pull the instrument cluster out of the vehicle , find a wiring diagram an check the instrument cluster wiring harness an connector for bare wires an check for power an grounds with a DVOM - digital volt ohm meter !

07 suburban DIC not working and shift indicator very dim, shows sometimes.


{: ) There is an internal circuit fault on your instrument cluster. The messages will display sometimes, at times dim or none at all. The usual fix is to replace your IPC (instrument panel cluster).
A new replacement IPC will be of later model versions, and it will be programmed to your vehicle.

2000 olds silhouette - everything electric works strong but no instrument panel and won't start


It is possible that there is a circuit problem in the circuits that provide power and ground to the Instrument Panel Cluster (IPC), or the IPC itself could be internally damaged. The not starting problem is a direct result of the IPC not working. Your Engine Control Module (ECM) will not allow fuel or spark to the engine if the IPC cannot communicate. This is part of the security system that keeps theives from stealing parts out of your vehicle and using them in another vehicle. When you turn on the ignition switch, the IPC is supposed to communicate with the ECM and send it a security code. If the ECM does not recieve this security code from the IPC, it "assumes" that the IPC has been stolen and disables the engine to prevent the whole car from being stolen. If the IPC is replaced, the ECM has to be reprogrammed to accept the new security code from the new IPC.

Replace spedometer cable 2003 gmc yukon xl


There is no speedometer cable on the 2003 Yukon, if there is no transmission issues like shifting problem. Your instrument cluster has gone bad, to pinpoint. Your stepper motor to your speedometer gauge has failed and needs to be replaced. You can do a search on Ebay for the stepper motor for around $10.00 which is better then the $400.00 cost of another instrument cluster.
There was a TSB on the replacement of the instrument cluster for your Yukon free of charge. The only cost to you is the labor charge unless your willing to do the job your self.
