Its a pretty easy mod. The adapters make plug and play. You can use a wire tap (the instructions I just sent you uses a wire tap) but I have/can get a neat pigtail that will plug into the 315x so you don't need a wire tap.
You would not be disappointed with the results of the mod. I love mine.
PM me a price on the pigtails and bulb adapters...
