Hooking up temp gauge on Pro V

[Nucad]

I'd like to hook up a temperature gauge to my Pro V 150.
When I remove the engine cowl I noticed two spots on the cylinder head that perhaps would be suitable?

There is a couple of threaded but blind holes on each cylinder head. Would these be the correct spot to mount the sender for an accurate reading?

There is a location for temp sender on each bank. The section in your service manual titled "power unit" will identify these 2 locations on the schematic.

Thanks for that suggestion. I have the service manual, but not the owner's manual. I have looked through the service manual and can only find the testing procedure for the thermo sensor.
