Hi i have been trying to figure out the locks on a 99 GMC Serria. Im hooking up a Auto Page C3-RS665-2W there are two wires for the locks but the diagram to where i am suppose to hook them up is confusing. Where do i hook the lock wires at, And do i need to have relays for the locks?
It all depends on which style truck you have, old or new, if old style which cab style, 2 door or 4 door, and if it came with factory remote keyless. New style truck is Type A, old style truck can be either Type A or Type C.
Check out the Bulldog Web site at : https://www.bulldogsecurity.com/bdnew/vehiclewiringdiagrams.asp and look up your truck. Then look for the wires at the locations they list. Use a DMM to verify the wires.
I am not familiar with the AutoPage R/S's, but Type A should be no problem to hook up. Type C might require relays.

Hi ok I looked at the bulldog site which was very helpfully if I was to have to use relays how should I wire them and do I have to disable the factory keyless entry
If you have Type C, check out the Door Lock Relay Wiring on this site for 5 Wire Alternating 12 Volts Positive Door Locks at https://www.the12volt.com/doorlocks/page3.asp#5w. Scroll down to the correct diagram.
This Bulldog install manual has a nice diagram of the relay install on Page 9, Type C. https://www.bulldogsecurity.com/pdf/RS102_112_122.pdf You can just buy the individual relays and wire them up using your R/S's (-) lock/unlock outputs and connecting to the correct wires on your truck, you don't have to use their "778 Relay" kit. You will need 30/40 amp SPDT relays and a fuse holder.
Some R/S units can support this style of locks directly (Type C) without extra relays, like Bulldog RS1100 and DEI ReadyRemote 24923. I am not familiar with the AutoPage unit and can't find an install guide for it to help.

After correctly installing the R/S to the door locks, the trucks door lock buttons ( and factory remote keyless, if equipped ) will still function normally. ( Of course, this assumes that your truck came with factory power door locks. )

lock - light blue (+) @BCM
unlock - white (+) @ BCM
bcm is located behind the drivers side of the dash.
if the autopage unit only has negative outputs, you need 2 relays and wire them like so
85 - lock or unlock
86 - constant 12v
87 - constant 12v
30 - to lock or unlock wire.
