Ok, so I know where the relay is, but unlike most relays there is not a little diagram on the side telling me which terminal is which.
It's a 52 mpi sei. Relay is red in colour and has four terminals.

Any ideas? I was proposing to attach a simple two wire test rig I have to 12 v to see if the "click" is apparent when removed.

Haven't checked this exact relay, but often the load contacts are bigger than the the coil contacts.
