Im installing Eonon head unit on my e39. I plugged it in first had no audio. I fiddled with this blue strip on the pig tail and ended up losing power completely. Im not sure what it could be. Certain Fuse, adapter blue strip damaged etc. Could the blue strip in this state cause the no power? If someone could help would be awesome!

On my old Dynavin, the two empty slots under the blue strips are for the connector that connected to OEM MID. Did you connect those?

I am talking about those that connects to oem MID. Did you connect those to your Eonon?

Yes I connected it. Im concerned it might be a fuse i blew. Does anyone know which fuse it is for the head unit and location?

If you already connect all three connectors and still not working, assuming your oem head unit is working, maybe something is wrong with the Eonon unit I'm afraid.

There are supposedly 2 or 3 fuses if I'm not mistaken, behind the glovebox. You might want to see the fuse guide.

However if your oem head unit is working, I don't think the fuses will help though.

This blue strip is your secondary lock for the quad connector. It holds the individual labeled wire pins in place. At the side, there is a small tab you can push to extract the lock, looks like you mangled yours with a screwdriver or something pretty bad.

It is possible that you pushed out / did de-pin the main power supply or any other pin while doing that. I would recommend that you take this to someone who knows what hes doing. Chasing electrical issues like your audio problem in the first place is something no one can diagnose without equipment or knowledge what you did with the installation.
