CONFIRMED! 06-07 side markers do not fit with the stock cable plugs that are on 08+ models. So what do i do? i pop off my side markers, heat gun it to melt the glue a bit and pop off the lens to replace the bulb. It uses a 192 bulb for the side markers. (BTW you dont want to heat it too much or it will start melting, just a bit to loose up the glue for the assembly. Once you have it off stick your bulb in (be aware of the bulb size) you may want to test fit you bulb and the lens in before you glue it back on, i had a 18 LED bulb i was planning on using, but when i test fitted the bulb and the lens, the LEDs touched the lens.
I was afraid it may heat up the lens and also it wont glue back on properly. (ended up using a one LED bulb high powered)
BTW you want to test the polarity of the LED first before you put the lens back on, (if not you have to do this all over again)
ONCE all that is said and done. Glue everything back sit back for the glue to sit properly and place them back on.
Below is the a pic of my side markers LED
