89 multi-function conversion

Hi all,

The wiper switch in my 89 GT went bad on me today, wipers are stuck on even with the switch in the off position. If I play with the switch a little and twist it just right then they stop for a bit, but then come back on. New switches are crazy expensive, but I heard there was a conversion that could be done to use the 90 - 93 switches which are much much cheaper. However I can't find the conversion. Can anyone help out and post a link to a write up?

If anyone has a thought that it may not be the switch that would also be helpful. Thank you
