I used the R1 for mine, yes the white plug is just a straight plugin, the two yellows will go to the turns...I cut my connectors off and used them with the new light, you only need a single wire as the factory setup includes a ground which you won't need. Remember this is just a light...no harm will come from connecting it to the negative or positive...it either works or you have to switch it around...no harm no foul. I just double checked the right an left fuction before I soldered and heat shrinked it all.
