Here's a diagram that me and my m8 put together. Is this any good? Any recomendations?

Is the 32a fuse enough? I'm running a wallbro uprated intank pump. The original wiring stays in the car but this is only for the fuel pump.

 

Sorry that won,t work. 85/86 are the relay coil conections. 30/87 are the normally open relay contacts.

 

you need to put the battery positive to pin no 87 and an earth conection on to pin no 85. It will work this way. but the correct way is 12v live on to no. 30 fuel pump on to 87. and the relay control wires to pins no 85/86.

 

Here's the new diagram, is this better than?
