are you saying the number of terminals and the layout on your relays don't match the datasheet?

Yes, the diagram is wrong I think. I put power to one and tested it and no go. Has anyone messed with this relay? I tried wiring up the whole ROV and no dice. The motors don't turn and the camera is static. Any advice?

well, get out an ohmmeter and see if you can figure out which terminal is which. it shouldn't be that difficult.
