As you know, the running light/blinker on the front of the fender is a 3 wire so the smaller LEDs with 2 leads won't work. But, you can use the wiring from the side marker on the fender to run down to the grill and use just 2 wires. If you are running LEDs in the rear tail lights you will need to run a resistor in the wiring to slow the blinker speed.
