SPDT Relay
 

I need one for my hood pop solenoid, and I have the wiring positions from the step-by-step section on the trunk popper.
Unfortunately, Im confused.

30-solenoid +
85-ground/alarm point
86-12v
87-12v
87a-Not Used

So I just make two 12v connections? I use the same source?
(Since I want it to pop w/ the car off I can just source it from the battery.)

9/10 electrical confuses me
