In the second diagram in the lower right is that a fuse and not a relay?
I see so many I can't remember them all and there is not one here right now with that same box.
I am seeking the location of the power lovk relay in an 88 chevy silverado
Should be a Flat Type GM Relay above the Gas Pedal or on the Support above Brake PedalIt will have ORANGE, GRAY, BLACK, TAN & a couple of other wiresIt does NOT look like a conventional Square Relay

There were "two" methods used:Relay & Direct Switch, (that reversed the voltage & ground)
If there is no Relay in the position I posted, then you need to "back probe" the ORANGE / BLACK wire from the Driver Door Switch to the Convience Center "PWR LK"Then from "PWR LK" to the ORANGE / WHITE wire to the "ACC / BATT" Fuse in the Fuse Panel
The Door Switch "Reverses" the Voltage + & Ground -
At the Door Lock Actuator "two" wires
When the Switch is moved to the UNLOCK Position there will be Voltage +, on one wire & Ground - on the other wireWhen the Switch is moved to the LOCK Position, the wire that had 12 Volts + is now Ground -The wire that had Ground - is now 12 Volts +
