Starter relays. Top pic is for automatic transmission neutral safety. Bottom pic is manual transmission. I have used automatic trans relays in manual trans cars, and it just has that extra terminal thats unused. You cannot however use the manual trans relay in automatic trans cars because of the need for a neutral safety wire hookup.

Right, so I have an auto trans in the car, and the auto trans relay (your top pic).

However, I was unable to get the starter to turn over with the key (with the car in neutral) when the neutral safety terminal on the relay was connected to the wire that was plugged into it when I received the car.

Only by unplugging that wire and directly connecting that terminal to ground did I get the starter to turn with the key.

So that means I have a problem with my auto trans neutral safety switch right? Because I am effectively bypassing it and the car is able to start.
