Melted wires

[josh_2563]

2004 f250 6.0 xlt
My egr wires rubbed on Metal and grounded out. Then the wires melted together. The truck still runs fine but the tach, trans temp and coolant temp gauges are not working. Also the glow plug light stays on for a long time. The check engine light and check gauge light is also on.

I checked codes and got. U0155 ( lost communication with instrument panel cluster (Ipc) control module.

Does any one know where this is located on the truck? Could the pcm be bad?
No fuse are bad. Thanks for any help,

I suggest replace the connector pig tail and clear codes retest. It would help to also find out the cause of the burnt wires and fix the issue. May also need to replace the sensor/valve.

I fixed the pig tail. I paid a guy to do a egr delete and he zip tied the egr valve to the intake pipe because it was making a code show up.
The zip tie broke and let the egr valve bounce around and wear the wires till it gounded out.
It still had code after fixing pig tail
