Toyota Corolla DIY

When you open the box, you should see something like this:

Remove one bulb and one ballast along with their wires:

Take the bulb, and cut here. You can cut on either side of the grommet, doesnt really matter. just make sure you dont cut the wrong wires The piece on the right will not be used with this kit.

Next, strip these wires:

Grab the ballast, and cut off these two male prongs and strip the ends:

Next, connect the wires that you just cut and stripped. Red to Red, and Black to Black. I soldered, used heat shrink, and wrapped it with electrical tape.

Repeat the above steps for the other ballast and bulb.

Now, open up your hood and disconnect the negative (-) side of the battery. Remove your stock halogen bulbs and mount the ballasts. Here’s pics of where i mounted the ballasts:

Passenger side:

Driver side:

Now; using latex gloves, carefully insert the HID bulbs into the headlight housing. (sorry, no pic)

Next, connect the two wires coming from the bulb to the two wires coming out of the ballast. Next, connect the other plug coming from the ballast to the stock lowbeam harness. Make sure when plugging the ballast into the stock harness, it plugs in red to red/white and black to red/black.

Reconnect the negative (-) terminal of the battery and turn on your headlights!
