Question Battery Kill switch on 1994 1995

This is for all who have installed a battery kill switch on their 94-95 cars. I need first hand experience with this, as I am very unsure of how to hook this moroso switch up. currently I have a diagram on how to hook up the switch, however I beleive it is for a fox body.
So for those who know 100% for sure, and have gotten a kill switch to work, please reply to this to inform me everything that have to do to get this thing to work.
I have understood that I must run a wire to the starter, one to the battery, and one to the alternator, however I would not know how to go about splicing a wire into the alternator wire, or which one it would be? Also, Which post on the kill switch to use?

Thanks in advance.

no one would help me when i was installing my kill switch, so i'll help you. there's a better way to do it, but this is the easiest way.

from the battery working forward:

neg post of the battery gets a good ground in the trunk. pos post of the battery goes to one side of the cut off switch, the other side of the switch i ran through the car, through the firewall to the power distribution block on the inner fender well.

You know, this is pretty much what I did.
I have my battery currently in the trunk and grounded well of course.
I did what you were saying ran one side of the kill switch to the + battery terminal in the trunk. Then I ran another wire inside the car through the firewall to the Power Distribution box terminal. This ended up not killing the power to the car..actually did nothing.
Am I missing something w/ this?

i'm not certain what the NHRA rules state that the kill switch must do. what i mean is, is it supposed to turn the car off, or prevent the car from starting? mine prevents the car from starting, but if i throw the switch while it's running, the car doesn't shut off. doesn't bother me. my tracks' pretty slack when it comes to tech anyways.

I believe it must shut the car off from the outside while the car is running incase of an emergency, therefore I am 90% sure it has to kill the alternator...
any more ideas?

paluka21 is correct, you must run a wire from the alternator to the kill switch along with the + cable wire.

fiveptO,
now will this switch diagram come into play with an sn95 as well?
Our starter solenoid is ontop of the starter correct? The relay is inside the power dist. box, so Im assuming the position of the solenoid?
Also, I am very unsure of WHICH alternator wire to run the wire to, or do you just run the wire to the terminal on the alternator?

Dan,

You can run the 1/0 wire directly to the power distribution box using brass lug.
On the alternator side, you should run the wire from the switch directly to the alternator terminal. I belive you can remove the black/orange wire that runs from the alternator to the power distribution box.

Scott,
have you done this on an sn95 car? Or is this for the pre 94 5.0L motors? Reason I ask is because the wiring running from the alternator to the power dist. box has a black and white wire. So, do I just run a wire from the terminal of the switch directly to the terminal of the alternator?
So let me make sure this is right, one wire to the power distribution box, and another directly to the alternator, and one wire directly to the battery? What about the starter?
So this would make 4 wires coming from the two posts on the switch? Are both posts on the switch hot?
I know these are alot of questions, but I need them answered in order to get this thing to work properly.

thanks
DAN

UPDATE

I spoke with someone who runs Renegade in the NMRA and this is what I have found.
That I may need a switch with 4 poles on it instead of two. That two wires will be required to be run to the + terminal of the battery, and 2 wires for the ignition kill. So basically, run two wires from one pole to the ignition, and two wires to the battery + terminal.
In this case the alternator being the ignition, however I have a two wire alternator which means that I have been told to run the wire to the power distribution box, since this should cut power to the alternator and the starter since there is a positive lead coming from the box to these components.
However I did this exact thing, ran one wire to the + battery terminal, and one wire to the power. distr. box and nothing happened when the car was running and you flip the switch.

Any ideas?
Dan

Without committing heresy and being burned at the stake, how do the Cheby guys run their wires? They have had the starter solenoid on top of the starter forever, along with the one wire alternator.
