      Pretty simple if you LOOK at relay, heavy wires will hook to big lugs, the 2 small spades ar for low amps ie the 85/86 terminals of diagram.
      Now watch those diagrams as the relay has a diaode inside to damp voltage spikes into computer controls. The little arrow agains a flat line is a diode, a squiggly line would be a resistor, the diode will only clamp voltage spikes in one direction, if I see pic right the 85/86 termianls on diagram actually may have a +or - on them.
