Today I attached the EGT sensors to the exhaust.
I had previously located and drilled the 5/16" EGT sensor holes into the exhaust prior to bolting it to the engine. I positioned the sensors' holes so the wiring would point directly towards (at an angle) the egress into the cockpit. I ignored the recommendation to have the holes downwind of the exhaust pipes. A fellow HKS owner has his sensors in the same configuration and doesn't have any problems.
The EGT sensors are almost too long for my exhaust pipes. There is about a millimeter of space between the tip of the sensor and the opposite wall of the exhaust pipe.
Above you can see that I needed a wire clamp to hold the left EGT sensor wire in place.
I made sure that the right cylinder has both EGT1 and CHT1 probes connected to it.
