Hello all! I bought a 2012 Nissan Xterra Pro-4X that already had a CompuStar CM900-S installed. Everything seems to be working fine but remote start doesn't seem to be working completely. The vehicle will remote start but the AC/Heater and accessories do not come on until I put the key in the ignition and turn to ON. I am assuming that the person who installed it possibly tapped into the wrong place for one of the connections. What would I need to check to make sure it is wired properly for my AC/Heater to come on with the remote start? Thanks in advance for any help!

Greetings.
I'm assuming that the current install is using the Blade-AL cartridge (not an ADS AL-CA bypass module). For proper operation the following wires at the vehicle ignition switch must be powered by the CM900-s controller :
Ignition 1 = White/Green wire @ Pin 3
Starter 1 = Gray wire @ Pin 2
Starter 2 = Light Green wire @ Pin 4
Accessory 1 = Red wire @ Pin 6
Accessory 2 = Green/Yellow wire @ Pin 5 *
* ACC2 should be powered IF the Xterra has Hill Assist to prevent the light from flashing during R/S.
On the CM900-s
CN1     
Pin 1 Red - Constant 12V        Green @ Pin 1
Pin 2 Green/White - Programmable Output     might be in use for (+) Parking Lights
Pin 3 Red/White - Constant 12V        Green @ Pin 1
Pin 4 White - Accessory 12V positive (+)        Red wire @ Pin 6
Pin 5 Blue - Programmable Output       **        Light Green wire @ Pin 4
Pin 6 Yellow - Starter 12V positive (+)              Gray wire @ Pin 2
Pin 7 Green - Ignition 12V positive (+)             White/Green wire @ Pin 3
Pin 8 Black - Ground negative (-) input            Chassis Ground
** Set CM900-s Jumper for Blue wire to START (default is IGN2)
I would check the CN1 to Ignition switch connections to see if the ACC1 Red wire is getting +12V during a R/S.
Soldering is fun!
