Anyone recognize this device I found under the dash?

I recently bought a 2013 Prius 2 from the original owner. When installing a back-up camera, I found a device under the steering wheel that is tapped into the wiring harness in about a dozen places, with diodes in several places. It's clearly not factory equipment. It's a small black box, smaller than a pack of cigarettes, with small wire coming out of it that may be an antenna. It has a 'min-max' adjustment on it. It's attached to the car with a zip tie. The box is labeled 769102 1106. There's no manufacturer or brand name on it. There's also a relay located behind the glove box.

The previous owner says she has never had any aftermarket parts installed in the car. She saved every piece of paperwork for every service done on the car since it was new, and there's nothing in that record about any alarm or remote start installation. I'll try to upload some photos of it. I'd like to disconnect it but it's so intimately connected to the wiring harness that I'm afraid I will disable the car in the process.

 

I found out what it is. It's a dealer installed security system, made by a company called KARR. Evidently some dealers install this system on all their new cars. It allows salesman to access all the cars on the lot with a single key fob. Then when they sell the car, they put a lot of pressure on the buyers to purchase the 'upgraded' security system. It's really not much of an upgrade over the Prius factory security system and they try to sell it for up to $800. If the purchaser declines to purchase it, they 'disable' the system but leave all the hardware in place. Here's an article I found about it. Google "never buy car alarm dealership" and open the first link that shows up.

I'm concerned about what happens if the system fails or if a thief gets hold of a dealer master key fob. It's tapped and spliced into the wiring harness in at least a dozen places, so removal will be a bit tedious and not without some risk of something not going back to together right, but I'm going to try and disconnect it so it can't fail or be hacked.
