    I'm only used to automotive relays.. anyways long story short I'm trying to figure out how to connect looking at the datasheets the layout is different then what I'm used to

    I'm looking at a SPDT relay

    most show where the coil is but what are the other points? I'm used to markings like 87, 30 and so on

    please post a picture of the relay showing the pins or post its datasheet.

    Here is the datasheet

    http://www.components.omron.com/components/web/pdflib.nsf/0/EB5C8B538D0F639485257201007DD57D/$file/G5V_1_0911.pdf

    and picture

    it's a SPDT so I don't know why it shows more then 5 pins

    5 and 6 are Common (that's like one pin only)
    1 is NC
    10 is NO
    2 and 9 is the Coil

    One more question I have this Fujitsu relay

    http://www.fujitsu.com/downloads/MICRO/fcai/relays/na.pdf

    Ok so 1 & 12 is the coil, 4&9 is common?

    3&10 NC and 5&8 NO?

    Since I've had this new in bag just laying around for about 4 years I can use it but I just need one side of the relay.

    Looks like you decoded it right! The relay in your first post is a SPDT (single pole double throw) and the one in Post # 5 is a DPDT. You can put the contacts in parallel for a higher current rating, if needed, or use it to control two isolated circuit loads.

    So that's how I can get the full 2 A rating? it's only going to be used on something that going to draw only about 700 mA.
