I put in a dual fan set up running one with a mannual switch one the normal way i broke the sensor under the header on pass side put it in new.And i also made sure the wiring was good and put one on the intake made sure the fan was working but the dang thing still gets hot and wont kick on any ideas???? Oh yea the relay works too but the blk-wire with red strip on it looks a little lose where it plugs in the relay box but i checked it too and it turned out ok
