So I am using aftermarket relays for the fuel pump and the cooling fans on my subaru conversion, using the stock ECU. I have attached a picture of the relay diagram.

So, there are two circuits, an 'inner' circuit and an 'outer' circuit. The outer circuit is only completed when the inner circuit's electromagnet is active.
It is currently wired like this: The 'inner circuit' receives a signal from the fuel pump pin on the ECU which goes into terminal 86 on the relay. (and here is where i think it has been wired wrong), coming out of terminal 85 the wire goes into the ECU into a 12 volt power connection. This is for the 'inner' circuit which should ignite the electromagnet. --- I THINK THIS IS WRONG. ---Shouldn't the wire coming out of terminal 85 go to a ground? thus completing the inner circuit and cause the magnet to attract the arm to complete the 'outer' circuit.
I hope that wasn't too confusing, let me know. Thanks a bunch!
