Brad's Note
This modification is from Mike Caroll (aka TurboMike) and ONLY for 2nd
generation DSMs. This procedure will allow you to keep your fog lights
on while the
bright-headlights are on. This is his procedure, so any comments or
concerns with it should be directed toward him. He does say this was
done
on a '95-'96 Talon, so check before doing this on a '97+.
Stock Condition
There's a parking light relay which fires the parking lights, dash
lights,
etc and a headlight relay which fires the headlights, fog lights, etc.
Modification
Have fogs work with parking lights, not just headlights.
Parts needed
 |
Fuse holder with at least 3" of wire on
either side (Radio shack has a
blade in-line fuse holder for $1.60) |
 |
Any blade fuse, any amp & can be a
blown fuse (will be used to hold
a wire) |
Procedure
-
The 2G fuse box (the one
under the hood) holds the headlight and taillight
relays and the fog light fuse. When the headlight relay fires,
12v
is provided to the fog light fuse which goes to the fog light relay
(controlled
by fog switch). What we want to do is disconnect that circuit and
have the taillight relay power this fuse, allowing the fog switch to
work
normally when the parking lights are on and not just when the
headlights
are on.
-
Open your fuse box, use
guide printed on top to find the taillight relay
and the fog light fuse. Remove the fog light fuse and put it in
your
in-line fuse holder (or if its not a blade fuse holder, get a 15 amp
fuse
for it). Take any blade fuse, and cut it in half between the two
blade connections. Use one half and put it in the empty fog fuse
socket ON THE SIDE TOWARDS THE FRONT BUMPER after inserting one wire of
the in-line fuse holder. The half a fuse should be keeping the
fuse
holder's wire in.
-
Pull the taillight
relay. It looks like this:
Taillight Relay
| 1 |
2 |
3 |
| 4 |
| 5 |
-
Stick the other in-line
fuse holder wire into pin #4's socket and plug
the relay back in on the wire. Make SURE the holder's wire is
only
touching pin #4.
-
Power from the headlight
relay stops at the fog fuse (now with only half
a fuse in it), power from the parking light relay reaches the fogs
(still
fused by 15 amp fuse in the holder) through the fuse holder.
Options
-
Daytime running lights:
Instead of plugging the fuse holder wire into the
tail light relay, plug it into the Radio fuse (SIDE CLOSEST TO FRONT
BUMPER).
This is in the lower left corner of the fuse box (on the turbo cars,
non
turbo in lower right, second to last) and it is connected with another
fuse (have to pull both together), you want the left one. As long
as fog switch is on, fogs will turn on when you put in key and turn off
when you remove key. Fog switch will work normally with key
in.
This isn't the greatest thing for your wiring, especially if you're
running
an after market stereo with an internal amp pumping out lots of wattage
(this fuse is the radio head unit's). The best way to do this
would
be to put a relay on this fuse, and have the relay power the fogs, but
I've had it on my car for a few weeks without blowing the fuse.
-
Fog switch ALWAYS works:
Don't know why you would want to do this, but
someone asked. Plug the fuse holder wire into socket #5 of the
tail
light relay instead of #4. Warning: you wont know when your fogs
are on or off just by the switch, if you accidentally leave them on
when
you park, there goes your battery.
Warnings/Tips
 |
If your car (or Universe) explodes,
don't blame me. |
 |
This was done to a 95 car, with a 95
electrical manual. It will hold
true for 95-96 turbo and non turbo cars but 97+ has subtle wiring
differences.
Please check your electrical manual if you have a 97+. (or just check
everything
anyway, maybe I typo'd or messed up) |
