Did search but came up with nothing. Please help I bought a speedinc. inline fuel pump, Im trying to install it but cant figure out the wiring on the relay. When I did a search I found a couple of diagrams for a 4 wire relay, but mine has 5 wires.. Does anyone know how to wire one these up? I know one will be the main 12volt power source, one will be a ground, one will go to the pump for power, one will be the gound for the pump, I cant figure out what to do with the last wire. Also Im not 100% sure thats where those wires go also. Please help ASAP.
Thanks,
Vann

#85 and #86 are used to switch the relay on and off. They are for low current power and ground (doesn't matter which) that you will switch with whatever switching signal you prefer to use.
When the relay is OFF, the two terminals #30 and #87a are connected, but #87 is open.
When the relay is ON, the two terminals #30 and #87 are connected, but #87a then becomes open.
If you only needed a 4-terminal relay with no normally closed connection, then you would simply tape up the wire from #87a and not use it.
The device you are trying to control with the relay would then be wired to terminal #87.
Your power source for that device would then be hooked to terminal #30.
When you supply power (from your switching source) to #85, and ground to #86 (they can be reversed), then the relay will switch and connect terminals #30 and #87,
and your device will get power from whatever terminal #30 is connected to (normally a fused source from the battery).
