Mazda3 HID Installation - Remove DRL from Lowbeam/HIDs


This modification keeps the HIDs OFF when:

1) the headlight switch is set to OFF
and
2) the headlight switch is set to AUTO and there is daylight, or it is bright, outside.

The relay must have the following connectors:

30 - +12V fused power source
85 - Ground
86 - Switched input
87 - +12V output (to headlight +ve)

The relay can be found at any automotive supply store (i.e. Canadian Tire), any stereo shop, or your local Radio Shack.

There are dual 87 connector relays available so you only need one relay to power both headlights/HIDs.

Wires and connectors can be found at Canadian Tire and/or Wal-Mart in Canada. Recommended minimum wire be 14 gauge. 12 gauge would be good for the +12V fused power (30) and the ground (85).

Note: Ensure that the headlight switch is set to OFF before performing the steps below. Further precaution would be to disconnect the -ve battery terminal.

1) tap into the orange/blue wire of the parking light/turn signal connector. NOTE: The orange/blue wire is the parking light wire and does not blink with the turn signal (a good thing). Using a female connector at the end of the tapped wire, connect it to the male connector 86 on the relay.

2) Using a female connector at the end of a wire, plug it into the male connector 30 on the relay. Splice that end to an ATO fuseholder. Splice the other end of the ATO fuseholder to a wire with a ring terminal at the end and connect that to the +ve terminal on the battery.

3) Using a female connector at the end of a wire, plug it into the male connector 85 on the relay. Connect a ring terminal to the end of that wire and screw it either to a body ground point or to the -ve terminal on the battery.

4) Using a female connector at both ends of a wire, plug one end into the male connector 87 on the relay, and the other end to the +ve (red) wire on the XTEC HID kit.

5) Connect the -ve (black) wire on the XTEC HID kit to the -ve connector of the STOCK H7 headlight harness (black wire).

6) If using a dual 87 relay, repeat steps 4 and 5 for the other headlight. If using a single 87 relay, repeat steps 1 to 5 on the other side of the vehicle.

7) Now that everything is wired up, insert a 30 AMP ATO fuse into the fuseholder.

8 ) Reconnect the -ve battery terminal and turn on the headlight to the parking light position. The HIDs should turn on. If not, check connections and ensure that the fuse is inserted fully.

To see that the DRL has indeed been disabled, turn the ignition on (start the car) and lower the handbrake. Normally, the lowbeams would turn on (HIDs would flicker); in this case, the HIDs should stay off.

To maintain DRLs, the independent fog light guide can be found on M3F or can be done at LOCKDOWN Enterprises in Scarborough, ON (647)-435-5896

Tap the Orange/Blue wire - in this case, the wire on the left


Tap connectors used to tap into the parking light wire. Orange/Blue wire goes in one side, wire going to the relay goes on the other side. Use a needle nose pliers to press down the wire stripper.


All done and wires hidden

Velcro was used to mount the relay inside the battery box.

where the connectors plug directly into the stock harness.


Polarion/Phillips HID kit

In a kit such as the Polarion/Phillips HID kit, which is wired like this:



All you have to do with the Polarion HID Kit is tap into the parking light wire and put it on one of the wires going to the \"to factory headlight plug\" connectors. The other wire in the \"to factory headlight plug\" is connected to the negative connector in the stock H7 harness.

The wires in the Polarion Kit going \"to factory headlight plug\" is the Switched Input on the relay (which is why \"polarity doesn\'t matter\"). The other wires are the fused +12V input, the Ground and the +12V output.
