Default Headlights wiring help

So my headlights stopped working??

I have STi reflectors and Hid's with an aftermarket harness/ballest to run the HID's

I checked the relay and fuse on the harness and found the relay had a little water damage(dont know how) so I replaced it and still nothing...

Checked the relay's inside the car and they are clicking over and have power, checkded the relays in the under hood fuse box and they are clicking over and have power in 3 spots(I believe). The fuses for the H/L's in the underhood fuse box do not have power to them. I am unsure where to go from here as I have no wiring diagram to chase

The aftermarket harness has power through the fuse going to the relay but nothing after it gets to the relay.

HID's, Ballast, and Harness are from SharpHID

The H/L switch/turn signal stalk has a little play in the end to where in the "on" position I can mess with it and it will click the relays inside the car, Dont want to waste $60 on a new stalk till im sure that that is the issue...

I know the circuit is ground controled and ive cleaned/checked all the grounds in the engine bay so im covered there just lost inside the car without a diagram..

Any help is much appriciated as this is my DD and I do have to work in the Early AM sometimes so I need my H/L's haha

Thanks very much!

Just went and tried the H/L and they worked.. (68deg and the due was still out so moist air)

Tried them again after I let the car warm up and had the same problem as last night, none working H/L's.

My theory of heat was wrong so now back to tracking wires... I need a wiring diagram badly

It almost sounds as though the head lamp circuit relay(s) is/are going bad or have bad contacts.

Are the +12 volts leads powering the ballasts connected to external (additional) relays designed to handle the additional current of the HIDs? Also, are the power leads (again, +12 volts) from the relays connected directly to the battery?

Be certain you are using two (one for each HID circuit - - left and right) external relays as the momentary starting current for each HID lamp is about 28 amps - - the contacts in the stock head lamp relay(s) are rated for about 10 - 15 amps and they will fail after a while. Also, connecting the power leads for the HIDs directly to the battery ensures that you'll have a good, solid power source for the HIDs.

Yes I have a fuse protecting the relay for the aftermarket harness that connects the battery to the ballast...

I'm going to try the headlight switch, swap all relays with known good relays, and recheck the aftermarket harness for good flow through it

My headlight issues turned out to be a diode that ran from the DRL control unit to the headlight relays as a ground...

DRL control unit still isn't plugged in and the diode is after the splice for ground so shouldn't have been an issue but it was haha!

Man its good to have friends who know and have eletrical tools haha

Thanks for all the help for those of you that contributed...
