72 Duster Resurrection

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.

The pic you have of the starter relay is incorrect for your year. These relays shown require a good ground to the body, and have 4 connections at most. Batt to starter big lug terminal. Starter relay to starter solenoid smaller lug terminal. Ign sw hot, and neutral safety.
