Electrical isn't my strong suit but I'm learning. As I look at the little diagram on the side of the relay, what am I jumping with my handy-dandy paper clip?
Thanks a bunch,

The working terminals, usually 30 and 87.

Terminals 85 and 86 actuate the relay, that is, those are the terminals that close the relay and connect the terminal 30 to the load on terminal 87

The relay connects 30-87 when it activates, so you want to connect them with the paperclip.
