Locate the Suction Hose. The hose has (2) 90 Deg. fittings pre-attached in the correct 
position. One of the ends has a service port, this should be attached to the compressor. 
The other end will attach to the suction tube coming from the evaporator assembly. Use 
#10 o-rings and apply oil before attachment. 
Tighten all fittings. 
Locate female bullet connector that is supplied 
with the Hi-Low pressure switch. 
Cut one of the white wires from the pressure 
switch. Attach the bullet connector to this wire 
and plug into the compressor clutch wire.

switch along the suction hose and connect to 
clutch wire that was inserted through the 
firewall. 
Use ty-raps supplied and attach hoses to the 
tower supports.
