Temperature Sensor

I have a MyChron5 and my son drives a MicroSwift. It is not obvious to me. Does anyone know which temperature sensor I am supposed to buy for the exhaust and which connecting wire?

It will depend on whether you have the 2T or not. As far as which EGT sensor, you can get either the Heavy Duty one (90 degree bend), I ran that on my daughter’s Mini Swift, or you can get the other straight stick style.
