I recently bought a Morningstar Voltage Controlled Relay Driver
http://store.solar-electric.com/moredr.html
From their manual:

And some Sting Pro # RL-5X relays I thought would go with it:
http://www.allelectronics.com/cgi-bin/item/RLY-351/search/12V_SPDT_30_AMP_AUTOMOTIVE_RELAY_.html
But it is not clear how to hook them up. Each has 5 prongs, and a crude
schematic
http://www.loohan.com/relay_schematic.png
that shows which is + and - power input. Another prong is
labeled 87, and is not shown connected to anything. So which do I hook up
where?
I did also get a couple matching sockets. Each has 2 red wires, 1 orange,
one green, one amber.

    87 is the NO contact, 87a is the NC one, 30 is the common contact.

    Thanks!
    I'm also a bit confused my the Morningstar schematic.
    It has a PWR terminal, which I would normally interpret has live juice coming out of it, but also on the line coming from it is a V+ source. Does that mean I need to pipe in power just to get it to switch the relay?

    BTW this forum thing sez I'm a "Solar Expert" but I think there's some mistake...

    OK, I think I get it. That is where one puts power in for the entire unit.

    hehe.. yeah, I have not had time yet to work out all the various ranks/grades, so I just put everything at 25+ posts for now.

    If things ever slow down I will have time to finish up some of the little details like that on the board.
