Did the same mod.
Got the parts online though, a lot cheaper than the dealer...

I think you have to email a guy named Dusty because the part is not in the drilldown.
The lights were about $45 a piece and I went with a pigtail to hook it up for another $25 I think.
Tell him what you need and he will find it,I'm sure
