The problem with running the temp sender in the thermostat housing is that it only reads the water temp AFTER the thermostat has opened. Unless your running a fail safe thermostat, most normal thermostats fail in the closed position 99% of the time. In other words your engine can be toast before the temp guage even registers.
i agree, you'd be better off running an adapter for it to put it into the manifold.... the thermostat housing really is best for the old smog stuff to screw into.... the vac trees with the thermal diaphrams and such
