Instrument Cluster Wiring - 77 F250

[Iceberg-32]

Hello everyone,

New Member here. If this topic or solution is discussed elsewhere please direct me accordingly.

Problem: I moved from a 12-pin to 14-pin instrument cluster. The I have the new 14-pin connector and have figured out the turn signals and brights, I cannot complete the circuit for the rest of the gauges, i.e fuel, temp etc. I have followed the circuit on the back of the cluster to discover every positions function. It has become a nightmare. My Haynes manual has been no help, the wire colors are not even correct. So frustrating!!

Questions: Where can I find another diagram? Can someone take a pic of the back of their cluster and connector so I can see how your's is wired?

Thanks in advance for any help.

Hey Patrick,
I broke down and bought the factory truck manual for the dealers use. It has everything in it. I also bought the cd for ford truck parts. Between these two they will have your answers. Question why did you change to the 14 pin?
