Question

Answer 1

Yes you can hook it up to the coil but you will need a bosch relay as well.

The bosch relay will have five terminals.

30 is the common or input voltage to be switched.

87a is the normally closed connection. This terminal is hot when the relay isn't energized, it is unpowered the relay is energized.

87 is the normally open connection. Powered only when the relay is energized.

85 is connected to the ground of the triggering voltage.

86 is connected to the positive 12V of the triggering voltage.
