2008 Dodge Caravan Wiring Diagram

If you are asking about adding Remote Start...........

I recently did a Remote Start on a 2009 Grand Caravan.  I believe the 2008-2010 are the same.  It was very easy.  Plenty of room and the wires were easy to locate.

Use the IDatalink product ADS-ALSL-CH.  It comes flashed with the correct firmware.  Follow their install guide.  You can mate the R/S to the IDatalink module on the bench first.  It has the wire colors and locations that the ADS-ALSL-CH needs to attach to.  It controls everything, alarms, sliding doors, locks, parking lights and supplies a Tach signal, door status, brake pedal, etc....    All you have to attach to the car from the R/S is ground, +12 volt constant (battery), hood pin and horn.  The (-) horn is a Dark GREEN/ Violet wire found in the harness coming from the steering column.   The IDatalink module has 4 wires going to the TIP module and one to the parking light switch.  Programming the ADS-ALSL-CH is simple.
