No power to anything

Awesome, I thought that may be the case. I actually have two of them, but they were a little confusing.

The only power cable off the battery runs to a bolt on the starter. The starter has a part that looks like a starter but is smaller, piggy backed to it. Thats where all the wires for the starter run too. It is also where I used the screw driver to turn the motor over. From this peice comes a good sized wire that runs to this selonoid. This also appears to be where the outdrive power trim is getting its power. It would makes sense that this part is not working.

The part that is confusing is that there are 2 of them.
There is not much hooked up to the other, very old looking cables.

Do you know what each of the 4 post on the celonoid are for?
