Wierd Transmission Problem

I have a 1988 Wagoneer Limited that runs pretty good. I have two problems. I have brake lights but no tail Lights. I have replaced the headlight switch and brake switch. I think its the wires coming off the Brake switch that is giving me problems. I can't figure it out.

Second, My jeep sits at work and I Drive it once or twice a week. I went to get in it on Saturday, and went to put it in gear, and its stuck. The Little Back button on the gear shift won't push in.

Any help would be appreciated.

Thanks,
Daniel

Anyone?

I need to Fix it. I maybe Selling it.

Sounds like the nuetral safety switch for the tranny problem.
