Have you seen my post? I had to do the same jumper wire for when the starter wouldn't start. Since I have done this, I have not had an issue since. But this fix only pertains to models that have this plug. I know the 91 I had, didn't have it. So, I am not sure where the cutoff years are for this fix.
