I know this thread is a few days old but ill tell you what i do,this might also help someone reading this in the future, it does involve some extra work , on the passenger side when you take the wheel off there is a hole in the body that is a straight shot to the starter wire, at least my 91 Convertible has it.
Everytime i replace the starter i have hell with that wire and i just hate the whole process, here recently i decided to study the problem and find a alternative solution and that was it,i'm guessing its a hole thats part of the shock tower or somewhere in that vicinity? i had a picture but it was on my old phone that got lost.
