Temperature Sender

[Tom Hartman]

I have recently put together two cars for friends. One is a '69 SS 396 and the a '69 "Z". Both cars have consoles with gauges. The problem is both cars show they are running hot on the gaugeither car has overheated, just run up in the red on the gauge. I used aftermarket senders that have a blade terminal instead of the factory eyelet. When I changed the wire over, did I screw up the continuity in the wire? Thanks in advance, I am stumped.

I should have added, both cars are stock builds with new thermostats and clutch fans with shrouds.
