I'm not really sure... that's definitely not a stock Fiero thing... that's something aftermarket. Perhaps an aftermarket car alarm shock sensor? buddycraigg APR 21, 06:17 PM no clue. Are the wires hooked to anything? Jeff Roth APR 21, 07:31 PM All wires except ground were cut by previous owner so they aren’t connected to anything. If it is not stock, I will remove it. Thank you.

Thank you. It can be removed since it isn't stock but in my line of work, I've used something similar although yours looks home made. We set them on the floor of basements and if the water got up to those 2 pins, it would act as a short and set off an alarm. I highly doubt that the previous owner installed one but other than that, I have no idea what it is.
