In most ways the 1989 is pretty close to the 1987 and if there were any upgrades between 1987 and 1989 it should be in the 1990 manual.
Hope it helps you solve your problem.
If you need a new manual you can order on line a new set directly from Volvo
or you can go through your dealers parts department.
