Ok then, the low presure switch will most likely just turn on the pump when the pressure is low enough. Not having an el. diagram for this I am not positive about that, but it is the low pressure switch so it has to go into the low pressure side.
Therefore, put a tee in the low pressure line, with the straight through in line with the tubing. Attach the low pressure switch to the 90 degree part of the T
good to go
