Got the 1994 Fleetwood dimmer switch installed, it wasn't as plug-and-play as it is in that guide for a Cutlass, but I got it working.
The switch itself looks almost identical, connector has additional pin for 12V power, the difference is in the mounting bracket: It has same bolt pattern, but the switch is in a different location in relation to bolts, set back slightly deeper. There was some interference with other stuff when I tried bolting it, also the rod would have to be lenghtened by about an inch. Insterad of fighting with it I drilled out riverts and swapped the switch itself between the brackets, replacing riverts with bolts. I took the 12V from the same fuse I've added for DRL's which is powered on Ignition so I can flash the lights only when the key is on.
It is actually quite surprising that GM didn't install dimmer switch with a flashing function from the factory, that's literally just one wire missing and a switch with a secondary contact that activates when the switch is pressed in.
Green switch is the one I took out and replaced with the brown one. Last picture is the Cadillac switch on a SBC bracket.
