The autos do not have a safety switch....They have a sensor located in the trans itself that tells the ecu if its in neutral/park.....I believe its a 3 pin plug going into the trans itself,.....trace it and see where it leads.....You may be able to hook up a toggle switch..

To change the dashboard lights on a 1980 Trans Am, first disconnect the battery to ensure safety. Remove the dashboard bezel by unscrewing the necessary screws and gently pulling it away from the dashboard. Locate the bulb sockets behind the dashboard, twist them counterclockwise to remove, and replace the old bulbs with new ones. Reassemble the dashboard by reversing the steps and reconnect the battery.
The most common switch mounted there is the switch for the rear defrost. It could also have been a switch to power a factory supplied amp for the stereo. Most likely it is the first.
