Any idea what this is..?

I removed the ebrake console and this is sitting next to the brake lever, flashing... Wire runs off to the dash. Assuming it some old alarm system? Any better ideas?

My best guess is that's a glass breakage sensor for an aftermarket car alarm.

Tow- away 'jostle' sensor for aftermarket car alarm.

I can tell you without a doubt that is a DEI proximity sensor. It a field disturbance sensor.

Not glass breakage sensor btw.

Cool. It came with plenty of extra electronics. Old car phone set up, as well

Yup! Field Disturbance Sensor. These are great for convertibles where people may reach into the vehicle to pilfer something from your dash or sitting on the seats when you have your car parked somewhere. They could do this without bumping your vehicle . So this sensor sends out a signal and ones that signal is broken it lets the alarm system to usually "warn" first with a series of tones or beeps from the alarms siren. Then if the field stays broken it fires off the full alarm . The placement is perfect in the ebrake area as that the center of the vehicle and it will cover both sides equally.

Thats where they suggest placing it.
