I got this relay kit, and its a little strange. Its got some extra wires, in strange places... I dont have the install instructions, hoping someone could enlighten me. Why are there 2 trigger wires? Why 2 wires coming from the fuse?

 

30v coming from fused main wire.
85 ignition wire
86 ground
87 (other brands comes with 87A and I dont add fuse to it but not a bad idea) it allows you to control 2 items like a fog lights but use either wire for your e-fan. be sure to secure which ever wire you dont use to prevent shortage.
