Hello all, ive tried searching for articles but am new here. I have a buddys truck, 2005 2500 6 speed. Cluster and overhead console shows no bus and have no gauges. No blinkers or high beams. Scanned and has codes P1652 and P2509. Truck will start and run just fine. Have cleaned and check battery connections, also cleaned connections at ECM. I need some wiring diagrams so i can chase wires if that is available. I appreciate all the information on here and all the help!

There are 2003 wiring diagram in the 3rd gen articles section. That appeasr to be all we have.

I have a 2006 ecm/pcm pin out diagram of wires coming or going to ECM/PCM on side of block

Thank you i looked last night and found the wiring diagrams. Will try to check some wires one of these afternoons.

Do you care to share those? Ive looked at the diagrams in the 3rd gen section and they dont match the pin numbers and colors on the truck. The truck is an 05 and the diagrams are for a 03 so maybe thats the problem.

There is a 2005 FSM in the downloads section and it has wiring in it. 

 

Yes, there are big wiring changes from 03 to 05. 

here you go hope it helps
