Another Newbie with another question!

I found this 30amp 12v relay and I'm hoping it will work. Here is the specs:

Coil Voltage 12 volt DC
Contacts SPDT
Amp Rating 30
Terminals Push on
Size 1" x 1" x 1-3/4"

These are a lot cheaper than an Echlin ST85 solenoid.

Thanks in advance and for all the help I've garnered from this great site.
