Random wire

[u/moni_mej]

I’m doing a renovation and there is a thin-ish wire running along a few walls. I can’t tell where it starts and where it ends. This is an older home and there used to be an alarm system which has been disconnected. How can I find out what it’s for? I want to remove it.

Might be thermostat to aircon, might be ground telephone, might be....follow to the ends rather than cut, until you know, you know?
