Hello,

Automatic transmission has a switch located on the shifter, which is responsible for all the lights on the dash and the ECU operation. Refer to the pinout below, if you short Pins 9 and 4, Reverse Lights should come on, though before shorting those, you can measure continuity on the switch between those pins when the shifter is n Reverse, just to prevent some unexpected fireworks in your car.



Neutral Safety Switch is a little different, it doesn't rely on the transmission switch, rather on the switch built into the shifter lever in the interior. What I would do is simply re-wire a Neutral Safety Switch from said shifter to the Clutch Pedal, so that the starter would only engage when the clutch is depressed. It's the easiest, and in my opinion, the most solid way to retrofit one of those, since it is always a good practice to press the clutch before starting the car anyway.

Hope this helps and best of luck!
