Printer Friendly Forum Posts - Install LED

Hi everyone,

Been a while. I have a Mazda 3 2013, and installed some LED light strips in the front bumper. I want them on with ignition, but cannot find a wire anywhere that will work, and search on forums for IGN wire has proven unsuccessful. It seems finding one in the Mazda 3 is difficult, and not interested in tapping into a major harness nor trying to run a wire through the firewall to the cabin.

what I have found, is the headlight harness. However, there is no one wire that will ensure the strips are on in ALL the headlight control settings (eg. parking lights setting, auto, headlights full on, or DRL mode).

Note that this car has two separate bulbs for hi and low beams. Also note that the hi beams double as DRLs when the rest of the lights are off.

I currently have them hooked up using a standard 4 pin auto relay, using the low beam wire as the trigger. However, the LEDs will not work whenever the headlight switch in the cabin is on AUTO. For those who may not know, AUTO basically adjusts the lights based on the light outside:

- When it is light out (daytime), the hi beams come on at 50% power as Daytime Driving Lights
- When its darker out (night), the system automatically turns on low beams and all parking lights etc.

So, essentially, I need to use two triggers, the low beam wire and the hi beam wire. The kicker...the low beams stay on when the hi beams are turned on.

Could this be hooked up with a 5 pin relay, or am I looking at at a more complicated procedure? I get basic wiring hook up, but this is beyond me and I am at a loss.

thx.
