Re: DURTYEF3'S JDM Front End Conversion

--------------------------------------------------------------------
JDM Headlight Wiring

On to the wiring sides of things, first when i got the front end off the Facelift car i also managed to scab the headlight plugs which were a big help for me being able to have the headlights plug in and out like oem. (I've seen people hardwire their headlights, or individually plug each wire in, but for the more stock look i suggest you try and get ahold of some, of which shouldnt be too hard off a FL wreck or in the NZH Parts exchange.


First off for those that don't know...

PFL Headlight






FL Headlight




Okay so easiest thing first. Some may already know that PFL Headlight Harness (Thats the Oem wiring) does not completely plug straight up with the FL headlights,

Reasons being:

1) PFL park lights as in the above pics are in the bumper
2) PFL indicators are also located in the bumper where as they are in the actual headlights of the FL model
3) Most PFL don't have foglights (There are some which do, hence "some". As i found out yesterday mine was one of them that actually did, but they have been removed. Shot VT

Indicators

This is quite simple as i found out, hooking up the indicators between both headlights is a matter of disconnecting the indicator plug on the PFL indicator (Green & Black wires) and plugging them into the JDM FL Headlight

Unplug PFL indicator




Plug into FL indicator




(Note: I found i had to also use the FL housing which holds the FL indicator bulb, so try getting the bulbs/plug thingee when you acquire your headlights as it may help if you have the same problem)

Your indicator should now work Test it, but don't run battery flat like me. The same applys for the other headlight


Driving Lights

Just like the indicators, your able to use the oem PFL driving light connector with its FL counterpart.

This is the plug you'll want




This is where it goes on the FL headlight




And bobs your uncle. Your driving light should now work fine. If you do have problems check bulbs are not blown etc (one of mine were). The good thing is if you need to drive your car around during the night at least you have indicators and driving lights that are easily hooked up before you start getting down to cutting, twisting or whatever, soldering, heatshrinking, + conduit & electrical taping,(best way to do wiring like this IMO) takes a while lol

Before you start on the wiring for the rest, you might want to familiarise yourself with a diagram of the wiring of the JDM headlights.

One that's used religiously on Honda-tech




I dunno if it was just me, but i kinda had a hard time understanding ^ that diagram, but after completing the wiring, i then realised how easy it actually was. Ill try show real pics so its alot easier.


The Reason why you have to Re-Wire



JDM FL Headlight Plug Overview




Hi-Beams

You want to find the positive wire from the PFL Oem plug which is [Red/Green stripe] and snip that. Connect that to the JDM FL Headlight plug [Top Right]Hi beam Positive Pin. See pic below or (Pin #2 on H-T JDM Headlight Diagram )

Once thats done you'll want to also run the ground wire [Black] on the PFL Oem plug to the Ground pin on the JDM FL Headlight plug [Bottom Left] See pic
or (Pin #3 on H-T JDM Headlight Diagram ) Thats hi Beams done

Note: For the JDM Headlight, it uses the Hi Beam ground as the main ground for all the lights.

Positive Wire for hi-beams



Negative Wire for hi-beams




City/Park Lights

With the city/Park lights you need to cut the PFL plug off entirely as you can't use it for the FL plug. You'll have a Red (positive) and obviously Black (Ground/Negative) once you've done that.

Connect the Positive wire to the City/Park light pin on the FL headlight plug. See pic below or (Pin #5 on H-T JDM Headlight Diagram ).

The negative wire left over can be connected to the main ground of the headlight (Hi Beam ground) you just did earlier. Pic below, or refer to above.

Postive Wire for City/Parks


Negative Wire for City/Parks





Fog lights

Now the fog lights, First you need to get a few things before you start. You need a SPDT 12v Horn Relay which you can pickup for next to nothing or in my case $8 from Dick Smith. You'll need a 30amp Fuse Holder + Fuse, in my case i grabbed a In-line Blade fuse holder from Dick smith which cost $3 or something and had a spare 30amp Blade fuse lying around. (This is because i'm running a dedicated power straight to the battery, so need to have a fuse in there somewhere). You can splice into ignition or another power source which probly wont require the fuse. And a 12VDC 30amp Switch or the Oem Fog switch $

Note: The parts below is what i brought, you can use any variation of switch, fuse holder etc as long as the specs are the same.

The Relay



Buy one


Fog Light Switch





Buy one

OR you can use OEM one



Fuse Holder + Fuse


Buy One




Fog Light Wiring
