Title: How to change the reverse light switch on a 91 BMW 318is
Post by: Flipfury on July 04, 2009, 07:12:54 AM

Okay first of all you will need a reverse light switch which you can get for around 12 dollars. Once you have it jack up the car on the drivers side and crawl under a little more than halfway its on the driverside of the tranny up real high.
you will see 2 wires hooked to it. just get a firm grip on the end of the wires and unhook them one by one. Take a wrench and take it off and replace everything back. easy easy lemon squeezy. No mechanics needed!

I think this is my first post here - kinda late to the party.  I have to replace the reverse light switch on our '91 318is.  Is there a seal ring?  I bought the switch but didn't look in the box for a seal ring.  What torque value for tightening?

Thanks,

Scott Miller

Mine was on the passengers side and was missing the fuckin wires! I had to wire the switch back to the connection under the shifter and I had reverse lights. Sorry, had to chime in.

check the connection where the shifter is. Take out the shift boot and look for a white connector. Mine was just ripped off. This link helped me put:
