Using the pink wire in the 5 pin connector to the negative terminal of the buzzer to make a chirp when locking and unlocking. Not using the horn or a relay. The other terminal to the buzzer is a constant 12V+. Do I need a fuse on that wire? Or I guess I could tap into an already fused circuit.
 
The red wire needs a fuse or connected to a fused circuit.

Most people get one of these that includes a remote start.

Make sure all your connections are done properly. Solder is good. No wire nuts. Crimp connectors sealed with liquid tape.
 
^ +1. Yes, the buzzer needs to be fused. The red wire in the diagram needs to be fused anyway, so you can just tap into that wire to also feed the buzzer.
