Fog Lights Installation Procedure
For those of you that have the Gen4 cars...I did a foglight
install on an 07 Altima for an older gentleman, and had the
opportunity to shoot photos. This installation was done
using a new factory foglight switch, and the car was NOT
pre-wired for foglights. I did the installation with the
bumper on the vehicle and it took app 3 hours with photo
taking. Total cost on parts was around $350.
Parts Needed...
-OEM Foglight switch. Will differ depending on whether or
not car has auto light system
-Depo foglights. I found them for $175 for the pair,
shipped
Below needed if car is not pre-wired for fogs
-14g or 16g wire, 3 colors, 15 feet of each is plenty
-H11 pigtails, 2 (Pico p/n 5638PT)
-25 feet 1/4" split loom
-5/16" blue ring terminals (2)
-Blue butt connectors (4)
-Electrical tape
-Wire ties
-6mm Bolt w/washer. 6mm x 13mm long...1.0mm thread pitch
-(2) pins for fuse box. I got these off of a wrecked car's
harness...Not necessary, wires can be pushed into slots.
Tools Needed
-Flat blade screwdriver
-Phillips screwdriver (#2)
-Wire strippers and crimper
-10 mm wrench or socket/ratchet
-Floor jack, not necessary, but helps. I used the incline on my
driveway, ramps would work, or even putting the nose of the car over
a curb.
Check to see if car is 'Pre-wired' for fog lights
Easiest way to do this is to look under the fuse cover in the engine
compartment.

-If there are wires in the 2 positions inside the yellow box, the
car is pre-wired, this one is not

-Remove fog light covers
-Reach up on top of fog light cover and remove single bolt, 10mm
head
-No pic on car, just feel up there and you will find it

metal clip

bottom is for metal clip, tabs on sides are for alignment

-Pic of wires run into the fuse box.
-I uses a small screwdriver to push the existing wire loom to the
side and snake the new ones in.
-I used electrical tape around these wires inside the fuse box to
finish off and make look OEM

-The plug in the fuse box is of a similar construction to the one
shown below.
-This style of connector is meant to be serviceable and pops apart.
-Use a small flat blade screwdriver inside of slots to push the
locking cage on the plug towards the front of the connector.
-Insert new pins, paying attention to how the others are inserted,
and close connector.

-Now all that is left is to run your wires to each light.
-I used 1/4" split loom around the 2 wires coming out from the fuse
box.
-**Wrap the ends your split loom with electrical tape, it will stop
the wires from trying to come out. Same thing if you have a wire
exiting loom, but the loom continues on.
-I ran the power wires straight down behind the driver's side
headlight, and then across to the passenger's side.
-The ground from the passenger's side light comes back across to the
driver's side and both are grounded at a common point.
-I found this threaded hole on the driver's side, and while I know
it is a 6mm bolt, I am unsure of the thread pitch...about 1/2" long
with a washer on the bolt.

-Below is a pic after routing the wire to the passenger's side of
car.
-The plug shown there in the lower grille opening is for the outside
air temp thermometer on the car.
-There is enough room between the bumper cover and bumper itself to
tuck the 1/4" wire loom in there, and it will hold snugly. Look
where yellow line is, you'll get an idea.

-Turn headlight switch to on, and then the fog light switch (the fog
lights will only operate with the low beams on, and they also cut
out with high beam operation)
-Plug H11 pigtails into fog lights.
-Touch bare ends to power and ground wires before connecting
with butt connectors to ensure correct polarity.
-I wrapped electrical tape from the base of the H11 connectors to
the split loom.

Finishing Up

-Check your install again for any dangling wires, etc
-Pull car up to a wall and aim the fog lights by turning the
adjustors on the bottom of the lights.
-Replace all panels on car...
-**Fog lights can also be adjusted with the car reassembled through
this hole on each side
