How can I tell my ABS setup?

[James Morse]

I should have rear ABS as standard. 4-wheel ABS was an option. What should I look for to tell if I have 4-wheel ABS? Not a big deal one way or the other, I just like to know what I have.

Brakes work terrific, I haven't locked up rears yet in normal/medium-hard braking. They had just put new drums/rotors so assuming that's true, they -should- work good.

This is about the XLT.

Look in engine bay on drivers inner fender next to Brake Master, for this: https://www.ranger-forums.com/attachments/suspension-tech-36/88195d1501269039-4-wheel-abs-2-wheel-abs-img00115-20110226-1819.jpg

5 Brake lines, that's a 4WABS unit, if you don't see it then you have RABS

Thanks. I don't see that unit at all so they didn't get the optional 4ABS.
I can live w/out the optional 4ABS, actually could live w/out any ABS, really, and did for many years.
It can be nice in a panic stop I suppose.

Questions:
Since there is no unit there besides the master, where does the "pumping" of the ABS for the rears get done? I see the one sensor but I'd assume that's for the fluid level.
If I ever had the crazy idea to do so, which I doubt, could it be added? I guess there's have to be a sensor at the wheels... sounds like not worth it.

Follow the Front brake line on the Master down to the drivers side frame rail, it connects to the RABS valve
