Can someone tell me what this is?

I found this hiddem behind my radio. Ive seen it before, but I just left it alone because my new radio had the same plug connectrion.

I wanted to rewire it, becaue the way it stands now, it constantly recieves power.

What is this?

Swag..

I'll take a SWAG--(Scientific Wild Ass Guess!) --to me it appears to be an aftermarket radio noise supression "choke" filter,with its own fused power supply...of course I could be 100 % wrong...

I am not 100% sure, but looks like a transformer and a fuse. I have no idea why a transformer would be under there. It is probley a filter tho.

One-sided transformer is in fact a coil, aka a choke, and yep, that be a noise filter.

It will have no effect on the switched/unswitched nature of the wire. Fix the other end of it to address that.

Many times, noise filters/suppressors are used as a lazy subsitute for good ground connections. If you have any radio noise without the filter, try running the radio ground straight to the battery terminal, and see if that gets rid of it.

yep i work at audio express and we use pretty much those exact ones or a ground loop isolator all the time
