What is the difference between a automatic transmission starter solenoid and a manual transmission starter solenoid on a 1984 Mazda rx7 1.1 liter 1146 cc engine?

The main difference between the automatic and manual transmission starter solenoids in a 1984 Mazda RX-7 lies in their activation mechanisms and wiring configurations. The automatic transmission solenoid typically includes a neutral safety switch to prevent starting unless the transmission is in neutral or park, whereas the manual transmission solenoid does not have this feature, allowing the engine to start in any gear (provided the clutch is depressed). Additionally, the solenoids may have different electrical connections to accommodate these functions. Overall, the design reflects the operational requirements of each transmission type.
