Negative Horn Trigger on 2011 Town and Country

Question

My van did not come with remote start or an alarm so I am installing the Fortin Evo-One

that is a remote starter and alarm. The remote start works fine I just want to use the horn for the alarm side I need to know the correct wire color from the steering wheel column harness. On this site it has a color table that calls out a dark green/purple inside the steering wheel column harness but I do not have any wires with that color. I need to the correct color. I am assuming that the horn switch goes to ground on pressing the switch to complete the circuit. If they change the circuit on my van does that mean I have to use a aftermarket siren.

Answer 1

The horn does not have negative trigger in your vehicle, you either have to run under the hood and trigger the horns directly with a relay, or much simpler is to use an aftermarket siren.
