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.
