DOOR LOCKS-Due To Multiplexing,Each Front Door Is Individually Activated.This Is Accomplished By Using Two Pair of Relays Confiqured As Reversal Rest At Nothing To Control The Actuator Wires Of Each Door. GREY = LOCK,TAN = UNLOCK The Door Panel Must Be Removed To Access The Actuator Wires.To Opperate The Rear Passenger Doors- Apply A Negative Pulse to Pin #85 Of The Rear Door Lock/Unlock Relays Located Under The Driver's Dash. DATABUS: DataBus Door Lock Interface Module Is Available.Call For Details. DB-GMDL-4 Simplifies Door Lock Installation
