So this is still the LAST thing I am still trying to figure out.....I cannot find a wire diagram from the ignition relay inside the cabin to the Neutral Safety Switch beyond the firewall. I know where the Neutral Safety Switch is and I know it is a pain in the butte to get to. Which is why I really hoping to tap into that wire inside the cabin BEFORE it goes through the firewall.

Anyone have any resources to help confirm where that wire is before passing through the firewall?

Even if you just have a bookmark that has a collection of useful wire diagrams you have used in the past....anything might help.

 

Do you have a service manual?

 

I might....but lost it somewhere when we moved.

I should look at breaking down and buying one.

 

I thought engine immobilizer prevents the need for the kill switch? Just wondering.

That said, here it is (P29 = connector P wire # 29 - BLUE+Black) Transmission range switch = Neutral safety switch:

 

Thank you VERY much!!!!!!

That's right.

However, a thief would know that. They could still steal the car by:

• making a cloned key
• altering the PCM to recognize the thief's key
• stealing the owner's key (i.e. B&E the house)

 

Thank you for all the info! I am sure it will help once I get under the dash again!

And yes....that is why I want a kill switch like this. The most expensive car alarm in the world does nothing if the criminal steals my keys, steals the signal code of the phob, or car jacks me at a red light (happened to a friend in Portland, OR).

With this installed, If I am ever car jacked, or criminal steals my keys and uses them to disable the alarm, they still cannot start the car and will just keep tooting their....urrr....mine.....own horn everytime they try. LOL.

I just turn off the car, hand over my keys, and run. By the time they realize my car is useless to them, my supper strength running skills fueled by panic will have me half way back home by the time they turn the ignition and hear the horn honk.

 

route the power to the horn

I would install a similar kill switch if I thought my van was a target. Thieves are far ahead of stock anti-theft systems.

However, a thief would quickly become vengeful when the horn blared and they realize they have been pranked. You may still have the car, but the interior wouldn't be pretty.

FWIW, I would skip the sound and light show and just let them think the battery is dead.

 

A criminal who hates it when the tables are turned on them? I don't believe that has ever existed?!? (sarcasm)

As a former corrections officer I always found it so ironic when criminals get soooooo mad when someone does the exact same thing to them that they are doing to someone else. For example I booked a guy once for felony assault because he got so mad someone stole his car, found him, and kicked the @#$%! out of him. Of course I booked this same guy 3 times prior for stealing other people's cars in the previous 18 months.

I get your point though...and a very valid one..... but I do live in a pretty populated area suburbs...loads of good neighbors works all sorts of shift work so there's usually someone coming and going even at night. No matter at home or in a parking lot, the light show will get immediate attention. They won't have much time to react without some looking at what they are doing. I personally think the lights are better deterrent than a horn everyone has learned to ignore.....how many times have you heard a car alarm go off and never look out your window to check everything is okay? Now think if you saw BRIGHT flashing white / orange list flashing spastically with light bouncing of trees and houses 30 feet away and coming through your window? Bet you couldn't help yourself and HAVE to take a look outside to see what's going on.

As for the horn....have you ever heard a horn honk when you least expect it? Especially in the dead of night and already with nerves on edge. I worry more about if I have a biohazard cleanup kit to clean up what that guy might have unintentionally left in my driver's seat after that horn honks or the horns go off inside the cabin when he least expect it.....lol.... bet my car will stink for weeks!
