On my 86 they had been removed by the previous owner and in tracking down a working pair, fixing and reinstalling them I learned a few things along the way.
First and most obviously they will only work if you have a full size headlamp and not if you have the bumps that apparently appeared on DOT versions of some headlamps. Mine is the bulldog nose 86 with smooth lamp surfaces.
Second in 88 with the change to the newer swept lamp style the motors also reversed direction. Originally the motors would sweep inward on the final stroke but this was reversed to the more "common" outward sweep. I guess manufacturers realised it is better to have slush and snow directed off the vehicle instead of into the rad. The upshot is you will need a left and right motor and if you find earlier motors they are simply reversed.
Third, the wiring for both sides is there and in my case so was the plumbing/tubing which is slightly smaller diameter. They bolt up easily but to gain access you need to remove light housing and grill (but not rad). The plumbing itself is straightforward but you do need the check valves to ensure your fluid does not run out. There are tee type check valves (unlike 90 degree check valves) which you should scavenge - and which can be rebuilt as well if necessary - these are essential.
The motors themselves can be rebuilt and I have done so with several. There is even a site dedicated to doing it if you need the info. They run on a three cycle phase with the motor being turned on by pressure on the washer stalk switch and then off by an internal switch. If you find a pair of motors be sure to lubricate them thoroughly inside and bench test them before installing. There are three wires- ground, one to initiate the motor's movement from the stalk and the the third to provide power once motor is in motion. You could if necessary bypass the wiring and diy- the wiring should run from the washer fluid motor so look for it.
The washer nozzles sit on the wiper arms and can be directed for flow. They do an excellent job of removing everything but ice and the motor will stall (and possibly get out of synch or break) if you run them when they are frozen. That is why I think most people remove or disconnect them - so be careful.
The wiper arms - if you look closely - allow you to use shortened regular wiper blades which can be easily replaced but look closely on how they are built.
