02 silverado 1500 power locks???

I am new to this forum and I just bought a 2002 silverado 1500 regular cab. with 105000 miles and it is in fantastic shape. All fluids changed, plugs were in immaculate shape, no oil residue. Has manual windows/seats and i was told by the owner manual locks. 4x4 on the floor and factory SNOW PLOW PROVISIONS(VYU).
I just took apart the driver door panel to lube the tracks and there are electrical connections to the lock. Also there is an aftermarket engine start installed. When i hit the lock/unlock on the remote a relay under the dash clicks and the bell rings. Exterior lights flash as well. Inside the locks are a manual slide. I pulled off the fuse panel and from what i can see the

DRV UNLOCK Power Door Lock Relay
L DOOR Power Door Lock Relay
LOCK Power Door Lock Relay

UNLOCK Power Door Lock Relay
are not there.
Anyone know if i buy these relays and install if the power locks will work?
Do i need all these relays?
Thanks

I would bet that someone added aftermarket power door locks. Usually alarm shops will tuck all the wiring behind the drivers side kick panel. See if there is an alarm module under the dash.
