Need Info on Instrument Clusters

[Zachary Watts]

Hi everyone, I have a question about the inerchangeablity of the guage clusters from the 73-87 pickup trucks. The reason why I ask is because I recently changed out the entire wireing harness in my 78 to a wireing harness out of a 77. I am wondering if my 78 dash will work??? The dash is a warning light only type. But the 77 truck I took the harness out of had full instrumentation. I would use the 77 dash but it is broken and non useable.
