7. Lay the leads in the bottom half of the cable clamp, making sure that the fiberglass sleeving extends
slightly past the screw holes in the housing socket casting, (install new sleeving if necessary) then route
the wires as shown.
Important: You must follow the wire routing diagram to ensure that the socket leads do not interfere
with the lamp focus mechanism.

8. Install the top half of the cable clamp (17) and secure it with the two screws (18). Tighten the screws
alternately to ensure a solid connection.
Note: To ensure that the clamp holds the cable tightly, flatten the cable, then twist it a half turn
before you install the top half of the clamp. Make sure the top edge of the cable clamp is even with
the edge of the socket to prevent interference with lamp focus movement. Make sure sleeving is not
pinched.
9. Place the spring (8) on the protrusion on the inside of the index hub.
10. Join the two castings, making sure that the wires still conform to the wire routing diagram and are not
pinched between the two pieces.
11. Before proceeding, check again to make sure the green and white wires are still positioned as indicated
in the wire lead routing diagram. Adjust if necessary.
12. Press the two castings together firmly so the bottom of the light baffle (2) sits on top of the cable clamp
(17), then install the Z lamp knob (4). Hand tighten the knob all the way to the right.
Important: You must install Z knob as described above to ensure proper lamp focus travel.
