Looking for location of backup light switch for 1994 buick regal custom

It will likely be on the transmission.

Thanks for your response. When I looked at the part on Rock Auto website, they say its located near the gear shift lever. My gear shift is located in console between the two front seats.

I checked out their site and it looks like it threads into the transmission. Look at Part No. XRLS69, Back-up Lamp Switch.

Look at this for a Chevy Astro:

Notice it says mounts on transmission. All of them that I have seen have been this way.

Ok. Thank you. I will check it out.
