Randall is right. I performed this mod on my TR3A way back in 1980 and it
still works. I didnt have a functioal TR3 guage and Ebay wasnt invented yet!
The gauge I installed reads in Celsius. See the TR4 wiring diagram in order
to make the necessary wiring enhancements with the voltage stabillizer and
sensor. I was lucky. When I got my TR3, it came with an assortment of both
TR3 and TR4 guages along with a stabilizer.

As Randall said, they are always on Ebay.
