Hi Guys, Here is a very helpful tutorial. I had to wing it because I havent found a tutorial yet for the mz3, but I thought I would make one for everyone to know how to do this fantastic mod. Needless to say, my fingers hurt... i hate the retainer clip in the headlights.... but the final decision is that I LOVE HID's!!!! Tutorial Tools Needed: Phillips screw driver Flash light torque wrench ( optional) Right off the bat, Go order the 6000k Phillips HID kit, You wont be dissapointed. First thing is first.. let's inventory what we got: Very important to make sure I have the 6000k Bulbs. Yep I do! Yep, genuine phillips Alright the installation: Right off the bat, go read the awesome tutorial on how to take out your halogen bulbs. That saved me a ton of guesswork. But let's begin.... 1) Our subjected side.... Start by removing the 3 bolts that hold the plastic cover. Then remove the dust shield and take off the retainer clip. Go read this if you dont understand: http://www.mazda3forums.com/viewtopic.php?t=4139 2) Go ahead and wire everything up before installing. Saves a LOT of time, and there is hardly any room to work with in that small hood of ours. 3) Listen and listen carefully. The dust shield needs to be modified. I forgot to take a picture of what i am talking about, but what you need to do is cut out the middle part of it. Yes I know, cutting into your baby isnt what you want to do... but just trust me. It will make your life a LOT easier. This is what the setup SHOULD look like when you finally put them inside of the projector housing: ***VERY IMPORTANT TIPS***** The hardest thing to do is get the " bitch clip" to go over the plastic. You have to hold the plastic down VERY tight with one hand, and physically push that clip over the plastic until you hear an audible click. Otherwise, it wont hold and you'll hit a speedbump and there goes 600 bucks. Secondly, remember how i told you to modify that plastic shield? The reason is because the connectors need to go through the middle of that, so that they sit perfectly outside the shield, and the shield can go around it and slide back into place. 4) A GOOD GROUND IS IMPORTANT! A GOOD GROUND IS IMPORTANT!! A GOOD GROUND IS IMPORTANT!! Do I need to say it again? Bury this line into your head for the rest of your life. Here is a great place for the right side ground 5) Make sure you wire the battery connection properly. Remember: Red is power, black is ground. TIGHTEN AND RE-TIGHTEN THOSE NUTS!!! Any loose connections = NO HID's 6) Let's see if she lights up 7) Let's compare.... Stock piece of crap And God said let there be light...... I will take pics in the morning tommorow to show you were i mounted the ballasts, etc etc. Now go do the other side!!!!
