Should have been simple - but a few issues - like which cylinder is #1 (looked up the manual and the most forward cylinder is #1). Had to untie the bundles to track each lead and lable the far end.
Thought I'd recheck the Dynon sensor instructions - right at the end it says "Make sure the sensor is under the plug closest the exhaust ......". So had to pull all 6 plugs on the LHS and swap over the sensors.
Temp sender lables.
In place .....
Cylinder head temperature (CHT) sensor relocated to the spark plug nearest the exhaust.
