Does anyone know where/which wires in the GE8 are the ones that activate the parking lights? I have blue leds in my JDM mirror covers that I would love to have flash when i unlock/lock with my remote.

 

If I recall correctly from when I did my LED emblem experimenting, it wasn't too difficult to just take a look and follow the wires. I can post some pics soon if you need them, but have you just gotten under the hood and taken a look yet? You should be able to just follow the wires out of the light sockets.

 

I wonder if plugging it in directly to the light would cause it to stay on with my headlights. I wish I could do this, but LEDs are
Blue, and would be illegal to drive around with.

 

If you connect them to the parking lights, then yes they will be on whenever your parking lights are one. If you want to control when they will be on separately, you'll have to make a switch for them.

 

You could insert a relay... when the accessory line is powered (basically anytime the key is in and turned to I or II positions), it cuts power to the LED.

Which means you need a "powered OFF" relay.
