Are the side markers on a 72/73 FJ40 also blinkers?

I'm seeing some conflicting info on the web.

The link on Coolermans site and on the Autozone wiring diagrams both appear to show the side markers to also operate as blinkers however my side marker appears to be wired as a side marker only. I've seen other threads and info that state that the 72/73 side markers do not have blinker functionality.

The side marker on my 73 has 2 wires: a wire with a bullet connector and a wire that is grounded to the quarter panel.

I also noticed that the list/index on the '72/ '73 diagram on Coolermans site does not have a #3 in the list (which is where the side marker would be). Its got a number one and then both the headlight and the side markers are listed as number 2 in the list and on the diagram. (Not a jab at Coleman at all. I believe that he sourced this from a Haynes manual or something). Just trying to gain some clarity.

Thanks for any/all feedback!

Front side markers in the first one become Side turn signal in the second.
(And read side markers just disappear)

I'm not sure how a 1975 FSM wiring diagram is relevant to a 1973 model year FJ40. The OP identified his side marker light as having one power wire and one ground wire. It is not a blinking light on a 1973 model.

If there is only one green power wire from the headlight switch going to a lamp, and only one filament in the bulb, what would cause it to blink? Both of the diagrams above have a plethora of lamps marked front side marker light, front parking light, rear side marker light, tail light, license plate light, all fed from the headlight switch by a green wire. None of those blink.

Later model years (1975?) had front turn signal lamps that appear to have three filaments: one for the front parking light, one for the front turn signal light, and one a a side parking light incorporated into the lamp assembly.

Since I have a US market 1973, I'm answering the OP with what I know about 1973 US model year.
