OK...I built this 51 Merc ( NOT "Old Sckool").
It has a 95 Lincoln Mark VIII 4.6L 32 valve DOHC.
I've said this before and I'll say it again: I'm electrically challenged!
Coolant temp sensors: I've found 3 so far but I'm sure they are wired in the ECM.
I'm using Stewart Warner guages and I'm stumped where the temp sending unit should go.
