Hey RAJ42763@YAHOO. COM,

Perfect, thank you. What colour is the JC-2? That is the connector you are looking for.

Regards, Joe

I think it is black. How many wires go thru the connector. For the JC-2?

Hey raj42763@yahoo. Com,

From my previous reply I would hold off jumping a feed to the cluster for now, if you do this I would make a jumper wire and put a fuse in line. I realized after I sent this that you may not think to fuse the jumper wire. 10A fuse is right for the circuit which will stop you over loading it.

The JC-2 connector face diagram is below.

The white/black wire should go in and out of pins 19 and 20.

Check for voltage at both of these pins with everything connected and engine running as you have been before. Black wire on a known good ground (battery negative if possible)

If you have low voltage here like I said you then know the issue is between the fuse board and the JC-2 or its the JC-2 itself. If you have battery voltage in and out of the JC-2 then the voltage drop lies between the JC-2 and the cluster.

Regards, Joe

Okay, I found the JC-2 connection block. It is black in color like you said. So I checked it as you wanted me too. And On both pins #19 and #20. I only got 1.92 volts as you thought I would get. What is the next thing I need to do? Take the JC-2 apart or check the wiring between the fuse panel and the JC-2. Or do both?

Okay, I have found the problem with the instrument cluster and I have got it back to working like it is suppose to. Just to let you know where I found the problem it was the connection on the white/black wire on the back of the fuse #11. It was not making a good connection. "Thank you" for all your help on this problem.

Hey RAJ42763@YAHOO. COM,

Awesome! Really glad you found the issue there.

Voltage drop testing is tricky to start with and a bit difficult to explain in written format but you got there.

The purge valve code is an EVAP system code, it can take a while for this to fault again as the system is not always running.

Please do not hesitate to ask if you have any other issues. We are happy to help.

Best of luck with the truck.

Regards, Joe
