Don, I think you're right based on the old AirGuide wiring diagram. They seem to have two models, one for magneto and one for battery ignition, but both have matched senders.

Not sure why Louey, but your post did not appear before I started my reply even though the time tags show twenty one minutes between them. Had I read your reply I would not have bothered posting, but it doesn't really matter anyway, nor does the nomenclature for the device between the coil and the display - transmitter and sender are just different words for the same function, a transducer that receives a signal, massages it and then passes it on for use by another device. The important thing is that billy knows it won't work by itself, and like Mike P says, is it really worth it anyway??

I like calling it a sender better..........I can't spell transmitter.
