Whats the final word about coding needed or unnecessary? M5 area is saying it is absolutely needed but didn't say what it was and some here are saying that it's a clean swap and you're back on the road with no issues. What is is really? I want to order a set of the ROW amber signals but I need to know what is needed first before I drop more than a grand on a couple lights.
When I pulled my taillights off to get to the rear bumper nuts it was a single connection for each of the lights. I'd assume the ones on the actual trunk lid are just a single wire as well.
