I bought the a/n guage which has simple good looks.
My first clue of a problem was that the cht lead had one spade connector and one ring connector. Well there are only spade connectors on the back of the guage, so I cut off the ring and connected a spade.
During first run up neither cht nor egt worked. Through the jigs and reels I determined that the leads were reversed to the connectors on the back of the guage.
I swapped out all four connectors on the leads and now it works.
