Here are a couple cars with factory 69 power locks. They were vacuum on all 69 pontiacs (last year for vacuum). 69 was the first year power locks were offered on A bodies (maybe because the new A body based GP needed to offer them, justifying the engineering of the system for A body doors).

It is the same style as the electric window switches but it says lock in black fill paint and they are taller. The power window switches are square (same height as width) but the power window switches are noticeably taller. Also worth noting is that unlike power window switches the power lock switches have a left and right version of the switch.

First picture is from a 69 Catalina, the green GTO is Fremont built which had the switch mounted lower (i've had or parted 4 power lock 69's from Fremont), the GTO with the white interior is a Baltimore car, and they seem to have the locks mounted higher and more forward.

If you look at factory A body door panels they do not have perforations or indentations for the power lock switch but the do have them for electric windows and remote mirror. Fullsize car door panels do have the perforations. I guess it was due to super low demand for the option on A bodies.

all the above was negated if you ordered a Bonneville or Grand Prix with power windows and locks. Then you got armrest extensions with a bezel that housed both sets of switches. However if you ordered those two models with power locks but not windows you'd get the panel mounted switch like on the cheaper models.
