Hello new old guy here. I bought a 94 z28 yesterday. The gauge cluster is not functioning properly, fuel, temp, volt, and oil pressure. I found the gauge cluster has 2 rows of 17 pins and the connector has 4 rows of sockets. This wouldn't be a big deal but all four rows of the connector are being used. I am getting no feedback into the cluster from the sending unit, I have it at the connector but there is no pin in the cluster to connect to it therefore the gauge does not read.
Any Ideas what the deal is all the schematics do not show the two inner rows of pins.

 

Whoops, never mind. After I took the connector apart I saw what was going on. Got everything except oil and temp working. looks like I need a new cluster.

 

lol sounds like a cluster f@#k
