Hi, so I bought my car for a very low price from someone that had boughten it from a salvage auction, In the auction someone took out the amplifier, it has the logic 7 top hifi system, i found an amplifier used and bought it, I plugged it in and no go, after doing a little peeping around in the trunk, i found a bunch of wires that i believe are supposed to plug into something, I have ben searching for the last hour and cannot find what this part is called, one of the plugs is a large light blue one.

My question is what is this part called and where would be a good place to find one?

Never poseted pics on this forum, ill give it a shot heres one of the car, and one of the place where the part is missing.

THANKS IN ADVANCE YOU GUYS ARE AWESOME

Thats not the OEM amp, that's the TCU (Assist) and the phone and Sirius pre-wire.

Although I am pretty ignorant when it comes to these cars audio systems, I know thats not the amp haha. I really am just concerned about the place next to that thing pictures where all the wires are unplugged and it looks like something should be there, I don't know what part it is, and don't know anyone else with an e90 around me, So I am just trying to figure out the name of the part so I can buy one online, thanks!! and btw technic when I do get it figured out I will be buying one of your pnp harnesses. I just have no sound to any speakers as of now.

So, do i not need it?

My stereo system has the symptoms of a bad MOST bus circuit, would not having that be the cause? Also is there anyway to bypass it if so?

First off, you need to figure out what parts were on your car originally. Have someone run your VIN and confirm what all components/functions were there. Some of the pieces may not need to be physically replaced if their missing, but you may need to code them out or something, just depends. But I'd start with finding out what all features were supposed to be then verify the related parts for each function is present(if the function isn't working) and figure out what's left.

My car came with the top hifi system as stated, i assumed that all top hifi systems have the same components.
