Just bench tested these and will update the review in the future. A key feature of these CHT probes is 4 foot metal shielding, which allows splice insulation to survive outside of the hot engine compartment, compared to short lead parts.

I had to return the first one of these I purchased as it was defective. The switch only had 4 positions even though it had the right number of leads for 6 sensors. The replacement worked correctly.

Im glad I before cutting hole in panel. This is not a 2 1/4 instrument. Its only 21/16 . It might work in a 2 1/4 hole but would be really hard to center.

Works great! I initially bought the more expensive temperature compensated gauge which did not work at all. Apparently it was defective out of the box. I replaced it with this and finally have a gauge that works. Very pleased with it.

After installing the switch, the system failed to work. In checking the system for continuity using an ohm meter, we found that the factory installed connecter on the white wire to the gauge had not crimped the bare wire. A simple fix but a frustrating time sourcing the problem.

The casting of the case is unacceptable in any case (tso or not) The back plate still has spurs from the molding process. The back plate bows in the middle between all four corners. I have not installed or run this gauge, but not expecting much. This gauge would be OK at $30-40.
