Secon 2: Installaon of a Fuse Box Wiring Harness on a Pickup Truck
(For Late Model Ford, Toyota, or Nissan Pickup Trucks. Addionally, this wiring harness works for any
Chevrolet, GMC, or Dodge pickup trucks without the factory trailer towing package.)
1. Determine a Fuse Slot to Use
a. Idenfy an open fuse slot in the under-the-hood fuse box that will provide constant
power (baery power). For easier installaon, review the vehicle owners’ manual to
locate the horn fuse (or any other always powered accessory) and ulize the op
en slot
in the same row as that fuse.
2. Disconnect Baery
a. Disconnect the negave terminal from the truck’s baery.
3. Connect New Truck Box Harness to Truck Fuse Box and Ground
a. If you are ulizing a slot currently in use - as in the case of the horn slot - remove the
exisng fuse (select the fuse with 10 amp or less in rang) and insert it into the lower
fuse slot on the fuse end of the harness. Plug in the fuse end of the harness into the
selected slot.
b. If you are ulizing a slot currently NOT in use, plug in the fuse connector end of the
harness int
o the selected slot. Please note, if the fuse slot is not programmed to provide
constant power, no power will reach the truck box.
c. Aach the white ground wire from the harness to an exisng ground near the fuse box.
