Reply to "Why should I use relays in my Speedster?"

Ray, the 5 pin is the same as Gordon's 4 pin, labeled the same, with one added pin. 

Terminal 30 flip-flops between two terminals, terminal 87 and 87a. This is what's known as a SPDT, or single pole double throw switch(but controlled by a coil, becoming a relay). Terminal 85-86 for the coil are exactly the same.

No power applied to 85-86, there is continuity between terminal 30 and 87.

Power applied to the coil? Continuity between terminal 30 and 87a.

There can never be current flowing or continuity between 87 and 87a, unless somebody puts way more than 30 amps through the relay and melts it down!
