1. Disconnect wire from engine oil pressure sending unit.
2. Remove oil pressure sending unit from engine block.
3. From the parts kit, locate the brass tee fitting and pipe extension. Apply a
thin coat of thread sealant to the external threads. Install tee fitting and
pipe extension into same hole the oil pressure sending unit was removed
from. Tighten fitting so it's facing towards the rear of the engine, as shown
in figure 4.

4. Apply a thin coat of thread sealant to the oil pressure sending unit that was
removed in step 2. Install the oil pressure sending unit into the "T" fitting
as shown in figure 4. Tighten fitting. Attach the wire removed in step 1, to
the wire terminal on oil pressure sending unit.
5. From the parts kit, locate the oil pressure switch and apply a thin coat of
thread sealant to the external threads. Install oil pressure switch into "T
fitting, as shown in figure 4.
6. Locate the water temperature switch, on the right rear side of engine. See
figure 2. Remove the wire attached to temperature switch and connect it to
the newly installed oil pressure switch terminal marked, "no". Tighten
screw.
7. Connect a new 14 ga. Wire from Terminal "C" on the oil pressure switch,
to a good clean chassis ground.

9. If the fan relay is sliver, proceed to step 15.
10. If the fan relay is black, it must be changed to the silver relay supplied in
the kit. Proceed to step 11.
11. Remove the black relay. Disconnect all the wires from the relay terminals
if not identified with a wire number, mark the wires and which they were
removed from. Relay terminals are marked 30, 85, 86, 87, 87A.
12. From the parts kit, remove the silver relay and mount it under the drivers
instrument panel with 2 (two) - ¼" x 20-½” bolts, 2 (two) ¼”ID flat
washers, and 2 (two) ¼”ID lock nuts.
13. Cut existing wire terminals off, install new terminals supplied in the kit. as
described in step 14:
Wires F1 and F2 - Yellow ring terminals,
Wires F3 and F4 - Blue ring terminals.
14. Attach wire "F1" to terminal "1" of the silver relay.
Attach wire "F2" to terminal "4" of the silver relay.
Attach wire "F3" to terminal "3" of the silver relay.
Attach wire "F4" to terminal "2" of the silver relay.
Tighten all silver relay nuts to secure wires.
15. RECHECK ALL WORK BEFORE GOING TO Preparation for using.
