HELP! - 650SX Starter Relay?

Location
LKN
So I just received a new-to-me starter relay for my 650SX. Everything fits up, but where the old one has 3 wires plus a ground, the new one only has 2 wires plus a ground. Now my regulator has a spare wire with nothing to plug into it.

Is this something I can work around or do I need to start over? :dunno:
