You need to get the right bulb, most likely H1, and on my projectors I had to dremel out the housing so I could fit the bulbs in because the hid bulb is bigger than a halogen bulb took me about 20 minutes to do both sides

 

Was wondering if you guys had a wiring diagram for the projectors. I went to put mine in and the low beams didn't work. Any suggestions?

 

I have projectors and 12k hids in my 97 ram.

 

Do you have the wiring diagram or can you explain how they hook up?

 

Purple to blue
Red to red
Black to black

That is how my projectors are setup
