HID wire group and relay

Here is what get hooked up to what:

1. Connect to Left Ballast input

2. Connect to Right Ballast input

NOTE: 1 & 2 may be reversed depending on where your battery is and how long the connector cable legs are.

3. Connect to the Positive + side of your battery.

4. Connect to the Negative - side of your battery or to any convenient chassis grounding point. There is no difference between connecting the ground line to the battery or the chassis. Electrically, they are exactly the same. 

5. Connect to your car's stock headlight power cable.

Note: This connection can be to either the right or left headlight power connector. The other headlight connector is no longer used and should be covered in electrical tape or other material to protect the connector ends from the environment.

How it works:

The stock headlight power connector (5) powers the relay (6) which provides power directly from the battery (3 & 4) through a fuse (7) to the HID ballasts (1 & 2).

Got it?

Keep in mind that a Relay Harness is only necessary if your HID retrofit kit is a 50 Watt or higher kit.
