Enable inner halogen highs
with xenon highs DIY guide
Note (important): If
youŐre going to do this, disable DRLs or your DRLs will become high beams. If
you want the safety of DRLs use my always on fog DIY to make them function as
DRLs (http://homepage.mac.com/ianlindvig/drf.htm).
Another note: I donŐt know if
the diodes are necessary. I do know that the light control module is extremely
easy to screw up so I kept them with a better safe than sorry mentality
Also, there are two ways you
can do this install: (1) under the hood (easy but you then have wire taps
exposed to the elements) or behind the dash (much harder to find all the wires
but all your taps wonŐt see water). See note at end
For this you will need:
Project box
Rectifier diodes (may not be
necessary but better safe than sorry
Barrier strip (if using
diodes)
2 trigger (5 pin) automotive
relay (2x if donŐt want idiot light on dash)
misc electronic connections,
etc
1) Hollow out project box
2) Test fit to make sure
everything will fitÉ
3) Attach diodes to barrier
strip (note that you want to do this so you can run wires through without
making contact with the other diodes or terminals. The way show below is
probably your best bet. If youŐre skipping the diodes then just ignore this step
and the barrier strip completely. The triggers are what are gong to be going to
be going through the diodes to prevent any backflow into the triggers.
4)
The relay will have the
following going into it:
Power from battery
Ground
Trigger 1: original halogen
wire (to keep flash to pass feature)
Trigger 2: Tap from xenon
shutter
Power out (two wires, one for
each headlight)
Your cable lengths will vary
depending on where youŐre going to tap the wires. If under hood you must leave
enough length to run wires to headlights (with one power cable longer to get to
the drivers side headlight. If running under the dash (safer but much more
work) one wire must be about 4.5 feet long to go to the driverŐs foot well
area.
5) Connect triggers to
barrier stripÉ.
6) Connect from car trigger
wires to barrier strip (or relay if youŐre skipping the diodes
7) place in project box.
8) Seal project box, admire
itŐs neatness
9) No pictures because this part
can be done many ways. You must find your own wires. HereŐs the basics:
Color codes:
a) The right halogen power is
white with a blue stripe
b) the left halogen power wire
is white with a green stripe
c)
the xenon shutter is yellow with a red stripe (but be careful, trace the wire
as other wires share this color code
Process:
a) Cut one of the headlight wires. Take the end going to
the bulb and connect it to your relays power out
b) Tap the other end of the stock headlight wire to one
of your relays triggers. This keeps you flash to pass feature
c) Cut the other headlight wire. Connect the end going to
the bulb to your relays other power out
d) To disable an idiot light on your dash, connect the
other end of the cut wire to a second (otherwise pointless) relay (which, of
course, you must ground as well)
e) Tap, but donŐt cut, the xenon shutter and take the tap
to the other trigger on your relay
f) Use the positive batter terminal under the hood to get
power for your relay
g) Ground relay
h) Hide everything away
10) enjoy twice the nightly
light (which is hard to photograph):
