2003 Silverado Doorlock Wires

Can someone tell me the doorlock wires for a 2003 silverado. It has no factory alarm or keyless entry. Due to this I don't think I tie into the databus wire. Instead do I need to find the lt. blue and white wires at the bcm?? Are they (+) tap? thanks in advance.Dyer

Is this a Chevy? GMC?

Power Lock GRAY SEE TECH NOTES (BASE MODEL #201 Power Unlock TAN FOR DOOR LOCK INFO ** #201- See Nevitive Pulse Door Lock Diagram (Base Model).Lock L BLUE, Unlock WHITE Both Found At the B.C.M. Located Under Drivers Dash. 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. DB-GMDL-4 Simplifies Door Lock Installation <<<<is the omega part numberGood Luck

It is a chevy silverado 2-dr. DRAASCH.... Thanks for the post, but i'm afraid i'm a bit confused about which wires i need. Do i need to power up relays as if they were reverse polarity and tie into grey and tan wires, or are they a (-) tap on the lt. blue and white?Dyer

i went into the doors and found the actuator wires (tan and grey) they read +12 when popped lock and unlock. do i need to tap into these wires as if they were reverse polarity/actuator. Will this pop both driver and passenger doors? Any help would be much appreciatdDyer

see if you can find this part number where you live.......if not drop me a line...Good Luck

You should be able to use the blue and white (-) trigger wires at the BCM. I did an H2 that had the same wire colors and locations, and it worked fine with those two only.

sroth140..... Most 03 silverado's do need the 456g. However, this one is the very base model, so i don't think it uses the databus for the locks. chriswallace187.... I tested the lt. blue and white wires (same for my truck) and they didn't show any voltage change. It's strange draasch..... I found the actuator wires (tan and grey). They are + when locked and unlocked. Do I need to wire these up as if they were reverse polarity?? THANKS TO ALL OF YOU REPLYING ... WE ALL KNOW HOW NICE HELP CAN BE!Dyer

Just out of curiosity, were you testing the lt. blue and white wires in the purple plug?
