The temp gauge on my 55 Thunderbird isn't hooked up. There is a sender in the head, but the catalogs list two senders, 6 or 12V and I was hoping someone could enlighten me as to the difference and how to tell which is which. Will a 12 volt sender work with a 6 volt gauge given the voltage is dropped between the two, and finally, how was it wired, power in and out if the sender then to gauge then ground or the other way around? It is currently a 12 volt neg ground car, and the engine has been replaced, so no idea if the sender is original.



Thanks,

Don
