View Full Version : A little help with HID install

11-16-2006, 02:11 PM
I am planning out my HID install. going to be on oem proj 1 piece valeo's. i have a pair of 50 watt hid ballasts with D2R connectors. so i am going to get.

2 H7 adapater
2 9006 wiring connectors so i can have 2 wires coming out of the ballasts.

2 OEM Phillips/Xenarc bulbs

I notice that almost all aftermarket kits have wiring harness that connects directly off of the wires inside the bulb housing.. I was wondering if anyone have try just tapping/splicing the wires going into the harness.. if so.. does anyone know what 2 wires/color ? also does the wire harness just feed it with one ground or a ground for each low/high and parking . i figure it should be a ground for each then it should be pretty easy. just a matter of finding the right two.

I saw this from the tech article.


but i am a little confused.. according to that there is only one ground wire?


Tan/White (Low Beam) ¡VBlue Wire (2)

White/Black (low Beam) ¡V Blue Wire (2)

i am guessing the blue wire is for the new Headlights on the tech article so i should not worry about that..

now is that TAN/WHITE = 2 wires or just one wire?

i guess if it is just one ground i can just tap into it rather than slice.

should be one ground per ballast right?

One ground per ballast is best.

the oem wire harness that connects to the light housing... is there a ground wire for each bulb? high beam + /ground and then a low beam+/ ground ..

or are you guys just saying to use any ground point should work.. i installed alot of HID kits but i always just use the +/- that normally goes to the bulbs as the connection to the ballast..

Can i just use the + for the light sand then just ground the ground wire anywhere on the car.. i am just afraid that since it is like 1 million volts or something that if something screws up.. ten someone is going to get one hell of a shock. =o
