I have a 1994 Yukon GT 2 Door I'm trying to get the doorlocks to work on a Code Alarm 535 remote start with a 425a brain I think I have defined the the lock type as a 5 wire system one constant hot wire....... two wires always at ground.... and two wires that switch from gnd to +12v when pressed(unlock.lock) I've tried the circuit on this site and all it does is lock up the drivers door actuator any suggestions would be greatly appreciated

Power Lock	LT BLUE	Under Driver Speaker
Power Unlock	BLACK/ WHITE OR BLK/RED	OR Boot in Door Jam

2 SPDT RELAYS:

Cut LOCK & UNLOCK Wire in Half.
One Half goes to SWITCH
One Half goes to ACTUATOR

Relay 1

LOCK:
PIN 87 = 12 Volts ( + ) Constant
PIN 87a = wire from Door Lock Switch
PIN 30 = wire to Actuator
PIN 85 = Negative Lock Output from Alarm
PIN 86 = Constant 12 volt ( + )

Relay 2

UNLOCK:
PIN 87 = 12 Volts ( + ) Constant
PIN 87a = wire from Door UnLock Switch
PIN 30 = wire to Actuator
PIN 85 = Negative UnLock Output from Alarm
PIN 86 = Constant 12 volt ( + )
