Hi All:
Just installed cruise control in my '90 745 GL(Thanks John Sargent for your excellent instructions). When I removed the housing from around the steering column to replace the turn signal switch, I discovered that the switch was secured with torx screws, thereby making my right angle screwdriver useless. After a little thought, I realized I could use a 1/4" open-end wrench on the torx bit from the screwdriver in the tool kit. Worked beautifully. Hope this will help someone else.
