Alright, back to my bumper lights as promised. First off, our USDM front (grille) turn signals are both parking light, and turn signal due to a double filament setup we got from factory. JDM turn signals are setup a bit differently, using a single filament for the turn signals and a separate single filament for the "parking light."
Now our harness looks similar to this image I drew on paint.
There are two power sources: one constant and one turn signal, and obviously a ground. So I figured I'd plug the parking lamp to the constant, the turn signal to the signal power source and both grounds together using these Japanese motorcycle bullet connectors.
Although the male bullet connectors did not fit in the harness, I was fortunate enough to have the female connectors fit perfectly and hooked everything up. Of course, everything light up, but my turn signals were not functioning! My brother and I busted our backs trying to figure it out, but no results. My sole intentions were to not hack up the vehicle's wiring, and keep it as original as I can. Finally, my brother comes up with the idea of replacing the turn signal bulb to a double filament, but how? Being that I work in Autozone, I quickly remembered we sold bulb light sockets, so off I go to purchase these:
I was lucky enough they'd fit like a glove, except for some trimming in order to make room for the wiring.
Now it's time for the connection process,so I put both constants from parking light and one of the filaments from the turn signal together, while the one pulsating power source was reserved for the other filament of the turn signal. That pretty much did the trick! Here's a super short clip of it on.http://youtu.be/YmR0GZpnOu0
