Step 4Wiring the bulb
After it is extracted you need to use butt splice connectors to tightly connect both the standard and high beams together to a +12V and ground lead to be strung out the side of the projector. There will be three or four leads. Look through the glass to find which lead goes where, and activate both the regular and high beams at the same time. I used automotive connectors so I can change the bulb out if needed. To hook the PC power supply to the bulb connect a +12v lead (yellow) and a ground wire (black) to the automotive bulbs contacts. You will need to crimp, solder or use wire nuts because your dealing with a good amount of power. To power the bulb you either need a big 8+ amp 12v supply or use an old PC power supply. If your using a PC supply you will need to manually activate it or hot wire it.

Copy and past that link and you can see for yourself.
I was going to do the same thing, ie buy a used projector with no bulb and make my own, But I decided to buy one of the cheap Abis projectors off ebay.
I was very supprised how good these cheap projectors are.
But be very carefull. I purchased the Abis HDpro for £200 and it has two hdmi inputs, component, composite input, vga and tv tuner input. It handles 720p fine and 1080p with compression 4.3 to 16.9 aspec ratio in all formats. Some other makes don't have all these features. It saved me a lot of hassle trying to make one work the way you have.
But if you are trying leds I would look at the cheap led projector bulbs off ebay.
