I hate to be ignorant but what is the NSS? I am having problems with a brake light that keeps blowing. Is that what you are saying is that the line to the brakes and the starter relay line are touching each other?
I have a 95 Lexus LS 400 that will start and run fine in part or neutral but as soon as you try to shift it to reverse the starter re-engages. If you start it in neutral and put it in drive this doesn't happen. Any ideas on the problem?
