Locate the opposite end of the Heater harness with the yellow fuse holder, bare Red wire and the ring terminal on
14.
the Black (ground-) wire. Slide the bare Red wire into the closed end of the Tap Connector (you may need to open
the Tap Connector and pull the metal blade out of the way) and slide the Tap Connector over the Orange wire
on the upper 12vDC power supply. Install provided 15A fuse into holder. Photo 9. Route the Black ground wire
through the firewall to the mounting post of the terminal block. Photo 10. Turn the key one click (to acc.) and turn
the Heater switch to High and Low to insure operation. REMINDER: PUT THE FUSE IN THE FUSE HOLDER.
Connect the 2.00” vent hose to the Dash vents (occupant) with the heavy duty zip ties- then connect the open ends
15.
to the two outside ports on the Heater and secure with zip ties. Insert and twist the Air Wye into the center port
of the Heater and connect appropriate hose lengths from the Wye to the two vents in the dash pad/cover- secure
with zip ties. Photo 11, 11.1
Re-install the parts from Step 2. and secure all removed fasteners.

Fill radiator and burp-tank with 50/50 antifreeze or reuse the coolant drained in step 1. Start vehicle and lift the box
17.
to access the Supply T’ on the engine. You will need to loosen the #16 clamp closest to the engine and let the air
exit the system and re-tighten; while maintaining a minimum level of coolant in the burp tank. DO NOT LET AN
EMPTY BURP TANK PULL AIR INTO THE SYSTEM. This process will take 3-5 cycles of warm up/cool down and up
to 30 minutes, to clear the system of air. Keep an eye on the engine temperature and the High Temp warning light
(left side of gauge) as it will light up during this process. This is simply telling you that you need to begin the cool
down process and another cycle.
TIP: With the engine running you can loosen the clamp mentioned in the above step and evacuate the air in the system.
You will get air, steam, and a mixture of both- before constant antifreeze flows from the hose. Once this happens, tighten
clamp.
