I only had 2 wires coming from my led lights on the undertail
I left all my factory stuff in the undertail and just spliced the new wires so I have the option of returning to factory. I would go wire by wire and see what each one controls.
So you've got it figured out? I could help more, but my plastics are at paint and I can't really remember if there was anything else to it. Maybe mine had the integrator built in.
could you post the site you got it from, i'm in the same boat as far as being BROKE. trying to get the wife a house
lookin good bro
