6.
Route the wiring from each LED lamp to the T-Adapter and plug the connectors into the
connectors found on the T-Adapter.
7.
Use included zip ties to secure all wiring.

If you have determined your truck is pre-wired, jump to the Final Installation on page 4.
Otherwise proceed to the next step.
Installing Starkey 4572 Power Extension for trucks that are NOT pre-wired:
1.
Disconnect negative (black) battery cables from BOTH truck batteries. This is done by loosening
the bolt located on the side of the battery cable terminal with a wrench. You may let the cable sit
off to the side. Do NOT allow it to make contact with the +12v Red battery cable!
2.
Locate the rectangular vent behind the passenger side rear wall of the cab. If you have rear seats,
use the pull handle to lower the seat back. Pull back the insulation pad to gain access to the vent.
3.
Insert the power extension wire (the side with 2 Red connectors) through any one of the square
openings on the vent. The vent in that section will open.
4.
Feed roughly enough wire through the vent so that you can reach the T-Adapter. We will finalize
the exact length later.
5.
Remove the front passenger side door sill plate. You will hear it unsnap. This is done by pulling
straight up, starting at the front and working your way back. You will hear ‘popping’ noises when
the clips come loose - this is normal. See picture 2.
6.
Locate the interior fuse box. It is located behind the passenger side kick panel directly in front of
the door. If you have trouble finding it, refer to your vehicles user manual for the specific location.
7.
Remove the fuse box access cover.
8.
Remove the kick panel. It can be removed by first pulling upward where it attaches to the door sill
plate - one clip holds it in place. Then pull backward where it attaches to the door frame to release
the rest of the clips. See picture 3.
