May check with local auto parts store, purchase both the warning, and gauge sending unit from local NAPA parts store. There's an adapter for mounting both sending units, should be able to salvage one, I have not bothered, used 1/4" threaded steel pipe, found the brass too fragile, approx. 3' long and added a 't' connector and both been working great for past several yrs. Ran a solid wire from the respective sending units to the warning light, and gauge then connected the other side of gauge/light thru the CR unit, where current oscillates from 0-9 volts.
