This is just what I needed for hooking up my Mercedes GL to 4-pin U Haul trailer wiring. Worked great.

I have a 2006 BMW X5 that has fast blinking turn signals when I pulled my trailer with LED lights on it. I ordered this to fix that issue and this solved it. Everything now works as it should, however, when I have my running lights on and use the turn indicators I get a "check side lights" message on my dash. But as far as I can tell, everything is still working properly. So I'm good to go.

Just what we needed for our 2008 Audi Q7 to make led trailer lights to work

I thought that it would correct the led situation NOT change the configuration of the plug

Does it include a 3-2 converter? My Audi has separate wires for Turn & Brake. Does this product combines the Brake and Turn?

The 39008 is designed for use with vehicles already equipped with a converted 7-way trailer connector.
