Understanding the working of a relay will get you up and running.
-85 & +86 is the on/off switch to turn the relay on or off.
"GREEN(in/out spot 86)- to (+) Ignition?"
Connecting the Green wire to the Ignition wire of your car ( BLACK / YELLOW ). This connection means you will have +12V power going into the relay when the key in the cylinder and turn to the II position. Still following me? There is a I and II and start on your key cylinder. Take a look at it and check it out.
"PURPLE(in spot 85)- (-) negative when armed out What is this?"
When you lock the car with the remote. You will have a ground or - coming on this wire.
"YELLOW(out spot 87a)- Where's this go?"
"YELLOW/BLACK(out spot 30)- Where's this go?
nothing goes in/out spot 87"
BLACK/ white is your starter wire. Cutting this wire in half and connection the Yellow 87a to the keyside BLACK/ white side and connecting 30 yellow/black to the motor side of the BLACK/ wire is what give you the starter kill.
Basically, when you lock(ARM) the car with your remote. Your purple wire will have ground. Since your Green wire connection is to the Ignition wire. Anyone who breaks into your car trying to start your car without disarming it won't be successful because the starter wire will become OPEN.
Why?
When the relay is activated. There are no connection between 87 and 30. Your BLACK/ white starter wire being seperated by the relay (Starter KILL) on your vehicle has no connection. You Starter basically will not spin. In order for it to work the BLACK/ white much have connection on 87a and 30. Does that help?

Be careful whose advice you buy, but be patient with those who supply it.

helps VERY much... i understood the basic concept before you explained it in depth. I just wasnt quite sure on where the wires went and as far as why it's needed, it cleared that up as well.
Now... isn't there a way to wire the started killswitch so that the starter will only work if it's getting a signal from the alarm? i don't know how to explain it very well. I read shops won't wire it this way due to warranty and because people wont understand why their car wont start for a simple reason of a fuse blown...
Basically the starter gets power when the alarm is off and has no power when it is armed, so if the alarm is pulled from the car by the thief he has to rewire the starter to start the car, unless he hotwires it... instead of the normal way, if the alarm is disconnected the starter will still work?
Am i too confused about how this works? Maybe if you explain how this system will work the way it came wired from the factory i can get this cleared up. As im waiting for a reply i will be searching for the referance to how to wire up the starter kill 2 ways.... thanks in advance. AGAIN!!
