I expect 36sedan's right, as he generally is! My SPAL controller on the coupe has it's own sensor, and I chose to mount it in an intake port closest to the head, the hottest spot I thought, and then program accordingly. On an older manifold there might be only one port for coolant, so having one in the radiator would be perfect!
