can I use a spst relay to change door lock polarity- I am connecting the door module for a 2003 silverado and the paper work says to use a spdt relay but it dont wire up a 87a terminal, so I was wondering if I can use a spst relay without the 87a for this,they are the only relays I could find at radio shack, or should I keep looking for a spdt thanks steve
