Hi. Just been hardwiring my new intank pump and my twins in the boot. I’m just wondering which wire the trigger wire is that I’m going to use for the relays..there’s two small black wires and obviously one is the trigger but what is the other one and how do I differ them?
when the key is turned in the ignition one click does one of the black wires give out some current or what? Added some pics so you can see what I’m on about. Thanks

 

Oh man, I am not sure. My Evo III did not have that. At least not that I saw. Can you hit it with a multimeter to find out if it is the same as the other black wire? It is a ground?
