The 325 engine I am using in my Sportster has two engine temperature sensors, one with a brown top and one blue - both mounted in the thermostsat housing.

The question is are they BOTH used by the engine management unit - or can I replace one with a temperature sensor for use with the aftermarket temperature gauge I am using?

Cheers

Blue one is used by the ECU, the brown one feeds the gauge.
