so i bought a h4h wiring harness from password jdm

http://passwordjdm.com/PasswordJDM-H...-P971C320.aspx


now i know that the usdm has 4 wires, and the jdm has 3,

now the one password jdm sent me has 2 blue wires and one black ground wire.. how do i know which of the 2 blue wires are high beam and low beam?

its 1 black wire on the left, one blue on the top, and one blue on the right

help!!

 

i just hooked mine up but didnt solder them together until i figured out which one was and low

 

just letting you know that the jdm light bulb are dual filament in a single bulb.
usdm light bulb are single filament in a single bulb. by soldering (wire for wire) you have operational low beam. but when you do use that high beam, your low beam are actually still on. thus shortening out the life of your JDM light bulb for a mere 15-20minute life span.

i have done this before. use a test light to figure out which one is high/low. you should obviously know the ground wire.

 

using a test light tells you waht you already know though and thats which wires are high/low on the usdm harness side and you can tell that by the connector. Thus you still need to know which wire on the jdm pigtail goes to high and low

and to the OP. next time save yourself about 10 dollars and a shipping charge and go to your local parts store and buy the H4 pigtail harness its the exact same thing you just baught, they usually have them by all the lightbulbs and stuff

 

This is very simple. Thats a regular H4 harness and it wires the same, high,low and ground.

All your wires are there now except you will have an extra ground per side, hence 4 wires.
You still have only one +12 low beam, and one+12 high beam per side.

Use a voltmeter with headlights on to verify which wire gives you a +12.
The other wire is +12 highbeam
Black is ground

Next look at your bulb and verify which tab is low beam filament, if you hook it up wrong you will have your highbeams on as regular lights,lol

 

i wired min like this

_______ |HIGH BEAM|_________
|GROUND.................LOW BEAM|


this is looking at it from where the plugs match up. i copied the same wiring from my EJ8. i like how password rips people off by saying H4H harness when its the same harness as a 9003 (92+ civic), LOL

yeah ****ign password jdm lol i shoudlve just went to a junk yard

 

Well thanks everyone and i still have problems closing my sir hood -_- we tried pulling on the t-bar and it closed a little better but the sides dont close all the way yet.. i know u gotta modify some stuff.. anybody got any tips?

 

are you using an EF8/9 T-bar or a usdm T-bar? if your using a jdm one you have to loosen the bolts holding the latch and pull it toward the front of the car and re-tighten it again. also you might need to re-adjust the spring bolt on the hood. i believe its a 14mm nut, loosen it then move the bolt till it closes. tighten the nut before you shut the hood.

helps to have a buddy around in case the hood stays shut. they can pull on the latch from inside while you apply pressure to the hood and it will pop open.

 

how would i prevent this thus having only one on at a time.
not both hi and lows on.
i don't want burn out my bulbs very fast

 

i didnt want to deal with this so i just ordered some H4H hid bulbs for my headlights. this way i only run my low beams.

 

im using the usdm t bar.. we cut the T so its actually just a straight bar right now.. lol. my car doenst even have a bumper support right now so im actually trying to figure out which bumper support i should get.. or just waste money at passwordjdm.. for a sir bumper support. so if i have a usdm t bar can i just losen it and pull it? it closes but the sides look a little bit open

 

I have installed a JDM front end using the USDM t bar with washers and hood closes perfect!
I did have the guy order the JDM bumper support for 100bucks and made my job easier.
I still had to modify the JDM support by enlongating the holes. This makes everything line up 100 percent.
The US bumper support would need alot of modification to fit in the JDM bumper.

 

Yea all you needed to do was add washers. Enough washers to move the bar forward 1/2 inch and yur good
