I am thinking about adding sequential LED signal lights to the front of the car, and I was just curious what are the colors of the two wires I need to tap into to add signal lights?

You want to tap into the 3157 bulb, the two outside wires (teal w/ black stripe and black).. thats the only signal that doesnt second as a parking light

Just be carful to watch the resistance, or else your signal will blink too slow, or fast

I am wondering if it will be an issue??

The lights are oval in shape, and contain 35 diodes inside, just wondering if 2 of those would be enough to put the resistance out of balance?

Adding any more resistance to the stock incandescent 3157 bulb will make your blinker flash slower..

You could replace the bulb with an led one, like THIS (http://www.grandamgt.com/forum/showpost.php?p=1053257&postcount=1) ... then add the extra lights and see if that balences it out..

If it still flashes too fast just add an appropriate resistor and u should be all set
