04 dodge, avital 4200

installing avital 4200 on 04 dodge auto with diesel and has the black key. cannot get it to remote start no action at all fuses grounds and power good. also how do you hookup the door/alarm lock unlock. thanks for the help

Did you ground the BLACK/ white neutral safety switch input through the provided switch? There are a couple options for door locks, most of which require either a module or a good understanding of resistors and diodes (using the transistorized outputs from the brain to achieve the proper resistance values). To be safe I recommend relays. You would need 2 of them, wired like: Unlock Relay: Pin 30 Blue Door unlock wire from 4200 Pin 86 Constant fused +12V Pin 85 Out to vehicle multiplex wire, PURPLE / dark green in driver kick with a 330ohm resistor inline Lock Relay: Pin 30 Green Door Lock wire from 4200 Pin 86 Constant fused +12V Pin 85 Out to vehicle multiplex wire, PURPLE / dark green in driver kick with a 820ohm resistor inline If your truck is equipped with a factory alarm you can do arm/disarm and lock/unlock using the same basic setup but by replacing the 820 resistor with a 2K resistor and the 330 resistor with a 480 resistor and hook them to the PURPLE / light blue in the driver's kick panel and setting the unit to double pulse unlock.Installer, IT support, and FFL. I need less hobbies.
