Flex-a-Lite 778 without Controls Toyota Tundra Electric Fan Kit; 00-06 - Manual (Page 2)

INSTALLATION OF NEW ELECTRIC FAN SHROUD:
You will want to “pre-wire” fan motor wires & Vari-
able Speed Controller (VSC) to new fan shroud
before mounting to vehicle.
11. Careful planning will save time. Look at the wires
coming from the motors. The positives from each
motor will be connected together, as will the nega-
tives. Drill a ¼” hole through the center brace in the
shroud to pass one pair of motor wires through.
(see Detail A).
12. Place both red motor wires side by side and
smoothly twist together. Completely insert pair of
wires into one end of a yellow insulated butt connec-
tor. Crimp connector to secure. Repeat with black
motor wires to another yellow insulated butt connec-
tor (see Detail A). Red motor wire is (+) positive
and the black is (-) negative.
13. It is easiest to attach the VSC directly onto the front
face of the fan shroud. Using the holes in the con-
troller cover for a template, drill two 5/32” holes.
Secure the VSC with the two screws provided.
14. Drill two ¼” holes in the shroud where the thick
yellow & purple wires from the VSC will pass through
to the back side of the shroud (see Detail B & C).
15. IMPORTANT:
Insert yellow wire into the open end of butt
connector containing the two red motor wires
and crimp connector securely. Insert purple wire into the open end of butt connector
containing the two black motor wires and crimp connector securely. (see Detail C)
16. Mount bracket #77502 to driver’s side and bracket #77501 to passenger’s side of shroud. Use
the hex bolts and washers provided.
17. Lower shroud assembly between engine and radiator and loosely mount at top using OEM bolts
to original shroud mounting points. Note: Be very careful not to damage core.
18. From under the vehicle;
a. Attach bottom of shroud using OEM bolts to original shroud mounting points and tighten.
b. Reinstall protective skid plate.
