Wiring in a third tilt switch

[stuartsx5]

My boat didn't have a tilt switch on the cowl so I bought the Marpac surface mount switch off ebay.  I looked at the wiring on the motor (Force by Mercury 120 HP) and I found the wires coming in from the other switches (Blue and Green) to the relay.  My new switch also has a purple wire though.  Where does the purple wire go?  Is it a power wire and if so can I just hook it up to 12 volts where ever I can or should I look for another purple wire in the harness?  Also, can I just quick connect to those wires coming in from the other switches?  Thanks in advance.

Yes 12v to the purple wire.  Just tap in to the boat side of the starter solenoid/relay.

Thanks wrench.  I thought that was right but DC wiring escapes my understanding.  Sure will be nice to have that switch back there.

Thanks again.  Wired it up last night and it works like a charm.
