I'm hoping someone somewhere has some information on this.

I have a 99 GT. It has the T45 manual trans in it. The reverse lights do not work when I put the car in reverse.

I have replaced the reverse switch twice, once from AutoZone, and one from LMR.

So after tinkering, I can bridge the connector with a wire and get the reverse lights to come on. So I removed the reverse switch and plugged it back up and pressed the ball with my finger and the reverse lights work.

So obviously something...

Transmission does not engage reverse switch - 99 GT
