Hi Y'all,

A week or so ago I was querying about modifying my urS-car's frog 
lights to use HID bulbs.  To do that successfully I needed to be able 
to have them on and leave them on regardless of whether the high 
beams were on or not.

Success!

Modifying wiring to keep frogs on:

	Pull the fog light relay and insert a jumper across the two load 
connectors of the relay socket.  That's it.



Installing HID kit:

	Read the instructions provided with the kit.  They are sketchy but 
do caution you not to touch the glass part of the bulbs.

	Purchase a conversion kit off eBay for ~$40-$50.  I got a Xentec kit 
but others are available.  Specify H3 bulb and 5000K color 
temperature (assuming you want a bright white light rather than the 
boy racer "KEWL" purple look.  Remove the whole headlight (much 
easier to work on when it is out of the car).  Open the back cover of 
the headlight assembly and then pull the OEM H3 quartz-halogen 
bulb.  While there pull the brown ground wire circular spring clip 
which holds the brown ground wire to the bulb socket.

	Now install the replacement HID bulb in the H3 socket.  Locate a 
place in the case where the wiring from the HID bulb will easily 
reach and drill an appropriately sized hole for the rubber grommet 
supplied with the bulb.  Fit the grommet into the new hole with the 
ends of the bulb harness through the hole.  Also drill (or make use 
of an existing hole if you have already converted your low beams to 
HIDs) for the smaller two wire pigtail from the ballast.  Insert that 
pigtail through the hole and attach the RED wire (spade lug 
connector) into the spade lug vacated when you pulled the OEM 
H3.  Now clip off the circular connector and strip a short end of the 
brown ground wire and then crimp on a female spade lug 
connector.  Plug the spade lug of the black wire into the new ground 
lug.  Close up the back of the headlight assembly and plug the two 
sets of connectors to the ballast assembly (they only go one way).

	Now put the headlight back into the car (be sure the ballast and 
wiring, etc, precede the light into the mounting position).  Once the 
light is secured find a suitable location to mount the ballast 
assembly.  Double sided tape and/or small zip-ties are supplied for 
this purpose.

It's not a bad job once you know for sure the polarity of the ballast 
connections.  The RED wires go to +12V and the BLACK wires go to 
ground.  That was not immediately obvious until I finally saw the 
tiny + and - on one of the sockets with wires already attached.

Enjoy your new nice bright frog lights.  This will make frog hunting 
muck more productive.  ;-)
