Hey guys, quick question.
Do you think my daughter, who is somewhat mechanically capable, can DIY a brakelight switch replacement on my E34 that she is driving?
Any tips to make the job easier?

Long live the E34.

If she's young and flexible its a piece of cake, if she's anywhere near my age not so easy anymore.

There is an alternative repair on my website, see> Fixes - Brake calipers>>>E32 Brake Light Circuit Repair Interesting fix -- good photos http://twrite.org/shogunnew/topmenu.html
How to keep the contact of the Brake Light Switch clean of oxides. The extra current from the test lamp (about 0.3 Amps) cleans the contact. There is no need to replace the switch!
