I am needing a wiring diagram for the 2008 Civic SI so that I can install my siren. For example, there are wires for the following:
Hands Free Inputs (connects to the Horn Ring Circuit) used to toggle siren sounds from the horn switch instead of having to reach over and do it on a switch box.
Backlighting - connects to marker light circuit ?
Park Kill (will kill siren when you put the car in park - not sure how that would work with a manual trans) - connects to the neutral safety switch signal wire.
A wire to connect to a low current system switch - not sure what they are talking about here.
Here is a link to the installation guide of the siren.
THANKS AGAIN EVERYONE
