I have had my Hiace for a year now. Im looking into wiring in an alarm however I have no idea where to find the right cables I need to tap in to and redirect them to the alarm. can somebody please help me with maybe a guide or wiring diagram. im looking into the mongoose alarm with gps tracker. I supposes I need to find the cables that go to the indicators, door contact switches, ignition, fuel pump, acc, ect... It would also be great to know about all the spare connectors behind the dash board for aux switches as I have noticed them all around the van in odd locations and wondering if they are connected to the acc to uses as a relay coil to switch contracts.
