bypassing the neutral safety switch on my 98 GT?

Ohh Got it now.

You need to find the correct 2 wires at the Transmission Range Sensor harness and connect them together. I had to do this to my Saturn when I swapped the auto to a manual.

I found this on CrownVic.net

- remove the auto-trans DTR (MLPS/ transmission range sensor) from the original transmission, plug into the harness, and leave in the Neutral position to allow vehicle to be started
-Note, this should only be used a temporary solution as the vehicle would be able to start in gear
-The sensor should be mounted so that it isn’t just loose and flopping around - otherwise it will get damaged quickly. ‘Zip-ties’ may prove useful as a temporary mounting solution.
-The vehicle will not crank with this sensor (MLPS/DTR) absent, so make sure you don’t forget to plug it in and move to neutral during initial testing
