I'm trying to do the same thing on our 2 x3's and don't feel like spending that much on XTC kits. That's brush guard $$$ or other accessories. If you figure it out, please post!
I looked up a couple wiring diagrams and looks like it'll require 2 relays and some extra wiring to hijack the stock wiring for it to all play nice together. I'm probably just going to add a bulb to stock housing for blinker and call it a day vs drilling a bunch of 3/4" holes in my brand new rigs.
