Need Help identifying this small black box

I have a 2004 mustang Gt with the 4.6 motor I am trying to identify this small black box that was self tapped into my fire wall it’s definitely aftermarket. It’s connected to my main harness in the engine bay. I have zero clue what it is and it has little to no branding/markings on it. If anyone has any idea of what it might be I’d love the help

It [might] be a Mass Air Flow extender.

Can you tell if it's tied in with MAF wiring?
I honestly don’t know i haven’t looked to deep into the where the harness goes. It looks like an engine harness the power came from a red wire with a yellow tracer. I took some more photos I’ll attach those. I don’t know what wires it hooks into I’ll check soon I just have to pull apart that harness to check.

Do you know anything about the history of the vehicle regarding previous ownership.
I ask because that looks like a tracking unit (black box) used for fleet management (location, fuel, speed, etc) or Security device (GPS locator) or repossession tracker.

Check [if possible] if the wiring goes to the battery or the ECU.

Battery connection can indicate a possible tracking/security device and ECU connection possibly a performance tracker.

Just thinking out loud….

I honestly was wondering the same thing if you look I show where the wires go I the red and black were power and green and white look like they’re connected were spliced in to both ends of a cut wire I’m gonna do some more investigating into what wire it breaks the connection for I’ll post it when I know.

Does anyone know the name of this connector, I marked it with an arrow. I’m trying to narrow what wire that box goes to and it’s a green wire with a white tracer. I can’t figure out what that connector is so if anyone can provide any clues I’d appreciate it.
