5.0 out of 5 stars Great fit if you are good with connectors

I’ve seen people break the housing on the connector enough to fit it onto their harness and then zip tie it so it stays connected. But it’s so much better to just remove the factory connector housing and install the female connector housing the comes in the kit. That way it can be easily connected to the male connector that comes in the kit. I have a 07 BMW 550i, and after making this simple connector housing swap, it plugged in perfectly and worked great. Now I have sound again from my speakers since I bypassed the faulty Sirus satellite module

I ordered these bypasses to trouble shoot the radio system in my wife’s car. However, when I started to work on the vehicle I found another issue. So I was not able to use these. They look like great quality, fast shipping and great price.
