electric oil gauge

[frankyjoet]

Have 73 gmc p/u, would like to have help in installing an electric oil guage. I'm changing from mechanical to electric and the guage is in the cluster and am installing a complete cluster. This cluster is bascially the same except for the oil guage and in place of the blinking light when starting is a clock. I've checked the diagram in my gmc shop manual and it shows a pink wire coming from the fuse block to the guage and a drk blue wire to the oil pressure switch.
