Adding intermittent wipers to a non-intermittent truck

Adding intermittent wipers to a non-intermittent truck
My no-frills '91 has just the basic on/off wipers and I'd like to add the intermittent feature using factory parts, preferably junkyard sourced. I've read about the in-line relay located just behind the switch - is that all that's needed along with the switch itself? What about the controller that's located behind the glovebox? Is that different for the intermittent wiper option?
What about the year range? Did anything change over the '87 - '96 life-span or can any truck be a donor?
Any details appreciated...

Great, that sounds easy enough, assuming I find one of course. Do the '92 - '96 vehicles use an entirely different setup that's not reasonably transferable? Nowadays, these trucks are more common in the junkyard than the earlier ones, hence the question.

I saw nothing that looked like a module in the harness behind the switch on any of the trucks.
Was this a fairly rare option?

The intermittent switch I liked the most was in my '87 Mercury Lynx (my first 4-wheeled vehicle). It was on the turn-signal stalk, and there were 4 positions--off, intermittent, lo, hi. Then there was a separate dial on that stalk that adjusted the intermittent delay, with a little indicator window so that you could see roughly where it was set, even with the wipers off.

Thanks for the pic. I presume the "E7TF..." box is the delay module, yes? As close to the switch as it is, it should be easy enough to find (if the vehicle is so equipped).
