JDM Headlight Rewire (Thanks to Nissanrules)

The JDM headlights is different from the US spec headlights. The turnsignals are different as well. The JDM leopard headlights use a H3c bulb as a foglight (located where the US spec highbeam is) and uses the combo of H4 bulb for both high and low beam since it is dual filiment.

The US spec, uses 9005 as a Low Beam and 9006 High beam, both seperate bulbs. these are single filiment.

Thanks to deviant who gave me some info.
My friend Megesan who got me the lights.
My friend Justin for helping with the wiring.
My friend Joon for taking me back and forth to the parts store.
the12volt.com for relay diagram.
--------------------------------------
Here is what you will need.

-2 Relays (12volt 30A)
-electrical wire
-electrical tape
-butt connectors
-female plugs



-------------------------------------------------------------


IMPORTANT--- PLEASE READ CAREFULLY


This part, I'm going to show different parts of the wire up (jdm plugs/relay wire up)
***I AM USING THE DRIVER'S SIDE HEADLIGHT (US)*****




1. Where the High Beam wiring harness is.
2. Where the low beam wiring is, which is also has the wires for the turnsignal.
3. Relay.
------------

You will need to cut some electrical wire and put the female plugs in already. After that is done, find a place to put the Relay.

THIS NEXT DIAGRAM SHOWS THE RELAY AND WHERE THE WIRES CORRESPOND.


My relay set up



My relay tilted straight back.


1. To cornerlamp's Green wire with white stripe.
2. To foglight's Red with blue stripe wire.
3. Ground to body of car.
4. To battery.

US WIRING HARNESS

High Beam
- Red with black stripe wire
- black wire (ground)



Low Beam
-Red wit blue stripe wire
-Black (ground)



cornerlamp (bundled with Low Beam harness) MAIN PLUG
- Green with white stripe wire
- ground



----------------------------------------------------------------------------


JDM Plugs

Foglight (H3C bulb)
-red with blue stripe wire
-ground




Main headlights H4 plug
3 wires connect to the back.
-Thick Orange with black stripe
-Thin Orange with blue stripe
-ground


---------------------------------------------------------------------------------

The install.

-Remove the grill.
-take off screw on top of cornerlamp and headlight.
-take off bolts by the headlight near where grill was.
-take out screw underneath where cornerlamp was.
- cut after 9006-9005 plugs.
--------------------------------------

- after cutting your wires and add female plugs to the ends. (4 each side)
- install relay
-------------------------------------------

1. look at diagram and hook up ground (prong 3)and battery relay (prong 4) wires.


2. Hook up relay prong 1 and wire to cornerlamp's Green with white stripe.


-----------------------------------------------------------
Foglight Hook up.
-wire RED with blue stripe to relay ( prong 2)
- hook ground wire to cornerlamp's ground by splicing it.

-------------------------------------------------------------------

H4 wire up.




-Get both grounds from high and low beam and wire them together before you got to the h4 plug.


-Connect High beam wire (Orange with black stripe) to JDM h4 plug (Thick orange with black wire)



-connect Low beam wire (orange with blue stripe) to JD h4 plug with (thin orange with blue stripe).

-----------------------------------------------------------------------------

If you get headlights that dont have a plug, this might help you.

From the back of the plug, the high beam wire (Thick orange one) goes to the right side.
The low beam wire (thin orange one) goes to the top.
the ground seems to go to the left side.
---------------------------------------------------------------

I suggest that you test everything one at a time and with electrical tape. Once everything works, then solder and shrink wrap.

The headlights should work normally.
-when you turn on your parking lights, the foglights will come on.
-when you turn on your headlights, the low beam should be on by its self.
-when you flash or set on high beam, it should work just like a normal car.


Here are the differences between the corner..
The US cornerlamp is on the car. I'm holding the J spec one.
Reflector is different

This is what is behind the cornerlamps... notice the J spec one has a bigger bulb. US version has 2 small ones.
this will need some modification to the frame, you have to grind down a bit for the corner lamp to work.
