Locate the original wiring harness that supplied power to the original heater
motor. Measure 4” from harness and cut both wires (see figure 15). On the OEM
power supply wire attach a 1/4” insulated male spade connector. Within the
OEM fuse box upgrade the factory HEATER fuse with a 20 amp fuse (VERY
IMPORTANT).
Locate the bottom left mounting hole in the firewall that attached the original
heater motor. TEMPLATE NOTIFICATION! A handy drilling template is
included in this manual (example shown in figure 17). Tape the template to the
firewall, lining up the hole indicators for the OEM lower right heater hose outlet
and a lower bolt hole. From inside of the vehicle drill a 5/8" dia. hole for the
drain tube, and 4” round hole as shown.
CAUTION: Be aware of components like brakes (on the engine side) and
wires (on the interior side) of the firewall before drilling.
