I have a 4 pin relay and i'm connecting it to my alarm for start kill. I know wire 85 goes to the alarm (-) armed output (orange), wire 86 (has two wires: one goes to ignition wire and the other goes to the (+) switched ignition input on the alarm(yellow), wire 87a goes to the starter wire on the car, but where does wire 30 go which is green on the relay?

 

You cut the starter wire in two pieces.

85 alarm orange
86 looped to 87
87 key side of starter wire
30 starter side of starter wire
