GB, I was able to use the stock tail lights and plate light without cutting into the stock wiring harness.
I had to drill out the hole for the plate light and drill two smaller holes for their mounting bolts. None of it was tough.
I didn't want to go with the supplies LED lights and the resistors that come with the kit. I have this thing about cutting into wiring harness's.
The whole job took about 1/2 hour start to finish.
I bought it from a Canadian supplier for $115 (including sticker) and have the unopened LEDs if anyone is interested.
