Siren install

Question

Right now wiring is done per thar-one-toy16 harness i structions. I just ordered a siren and it says to connect the orange black wire to siren. Do i remove the orange black wire from the horn and reroute to the siren and connect black wire on siren to ground?? The aperntly horn doesnt chirp when remote start activates any way so im assuming orange black is reserved for alarm use??

Vehicle is 2023 tundra non hybrid

Answer 1

Orange/Black is a negative output, so it wires to the negative side of the siren.

Make sure to change option 12 to 12.4 in the remote starter settings as well so that the output is set for a siren (latched output) and not a horn (pulsed output).
