sidemarker wiring
 

i have got the fender cutouts good to go and i ahve the actuall password jdm wiring harness as well. my problem is how exactly do you wire the harness into the turnsignal light in your headlights? there is one red and one black wire per sidemarker per side.

Background info:
Our corner lamps are dual filament bulbs which have 3 wires:
Red +12V parking lamp
Green +12V blinker
Black 0V ground
(colors may vary, check your manual or use a multimeter)

The sidemarker has a single filament, which has 2 wires:
Red +12V
Black 0v ground


How do you want it to be wired? There are 3 options...

Option 1:
-Sidemarker is illuminated (providing your parking lamps are on)
-Otherwise, sidemarker is off (it will not blink)

Option 2::
-Sidemarker and blinker blink in phase (at the same time)
-Otherwise, sidemarker is off

Option 3:
-Sidemarker and blinker blink out of phase (alternate illumination)
-Otherwise, sidemarker is illuminated (providing your parking lamps are on)

How do you wire them up?
Option1-
Connect Red to Red.
Connect Black to Black.

Option2-
Connect Green to Red.
Connect Black to Black.

Option3-
Connect Red to Red.
Connect Green to Black.

The reason/how option 3 works…
When the parking lights are on +12V is on the positive side of the sidemarker and the blinker, being off, sends no voltage (0V) to the negative side. This +12V illuminates the bulb. Now, when the blinker is activated, +12V is observed on the negative side. This means that there is +12V on BOTH sides of the bulb, which because of the lack of voltage difference, the bulb turns off.
