Every so often while driving Ls I come a cross this problem when I step on brake the reverse lite comes on and I feel a slight resistance a tug. would like some feed back

 

There are one or more broken wires at the left trunk hinge. MANY previous threads on this issue and it happened on my 90 LS. Splice in new short lengths of wire into the broken ones and you are good to go. Do a search for past threads covering this issue. Many of the questions you may have about your 91 LS have been covered before.

 

Thanks for the info and I had some one look at it and they work in that area.
