Cut off Switch for Ignition

I am not sire if this is the right place so Im posting it any way.. please move it to the appropriate forum if necessary.

now, usually when we put the key in and turn it allllll the way up we get ignition, I want to make a cut of switch, (simple rocker or push switch will do that will have 2 wires to both ends of the ignite connection.. the car wont start if this switch is not on.

I want some tips on doing this right

Re: Cut off Switch for Ignition

Honestly I think thats just inviting problems you don't want to have. If you are worried about the safety of your car take it to a professional to do this kind of work or invest in a real car security solution, again, installed by a pro. Cut off switches and such aren't really something you want to be dabbling in if this is your daily driver...especially if you have no experience with this kind of things.

I see Renee is viewing this thread so my opinion may be null and void

Re: Cut off Switch for Ignition

Well, really, a kill switch is about the easiest thing you could do. Break the starter wire and put a switch in-line. The starter wire itself is just a relay control. Don't think there is much current on it. 1A ish?? for the starter relay. I assume you dont have a transponder key from the factory? I can't say this is something I'd ever do myself but it certainly wouldn't take a college degree to install properly.

Thats exactly what I was going to do but wanted to confrim with the "experts" here... so that I dont screw it up or something...

What do you guys say? should I just break the starter wire and put a switch inline or what? should I just get the el cheppo 1 amp normal wire etc ?

Re: Cut off Switch for Ignition

well... I wasn't going to get involved in this.... but... with some of the mis-information being flung around... Lets just say, I will "show you" the safe way to do this.

YOU CANNOT JUST CUT A WIRE AND ADD A SWITCH!
if you think you can... please make sure you have full coverage auto insurance and your premiums are paid!
______________________

Since I own the 4th Gen, I can tell you exactly where the wire is that you want to cut into and do this.. if you are going to do it right. As for the others? Well, consult your manual for the Primary Power Harness for the key cylinder.

I, Renee, aka" Lilmsprelude, PZ Forums, it advertisers, affiliates nor ANY members take responsibility for your actions and the results you achieve if you perform this mod.
AKA.. if YOU DON't do it right and your car burns ........... well,
I told you so!
You ARE dealing with very high current (sorry Jesse) and if this is not done correctly, you WILL Have problems.

First, REMOVE the plastic under side of the dash on the drivers side, then using a 10mm socket, remove the four bolts holding the knee bolster in place.
Now you need to remove the vent tubing.. just the long piece in the middle is OK.

There are two ways to do this I suppose.. it depends on the level of security you need...
This first method is the most extreme... and it will ensure that NONE of the Start/ACC/RUN circuits in the car work if the relay is not "on."
The downfall to this?? IF the relay goes bad for whatever reason... you are pretty much stranded.. OR, you would have to "jump" the relay points... A scary proposition to say the least. And if it went bad while you were driving... ya..... Just think about that.

____________________
Option #1
Now, the Primary wire that supplies 12Volts @ 80(+) Amps of current, is the Large 10AWG White wire.
If you click this text it will take you to the post with my pictures of my REM Start install.. scroll to picture #9 and you will see the back of the Key Cylinder- that large white wire is what we are going to cut power to. NOT At the key.... go to Picture#10 and READ the text under it.

That large white wire should be CUT and each end spliced onto a LARGE, HEAVY DUTY 100 to 180A (twelve volt) relay.
As pictured here.


DO NOT Use anything smaller than this... No, It is NOT ok... and if you are not willing to spend the money for a high current relay.. then why even bother doing this???

In this picture you can see a regular 12 V relay,on the left, like what you guys are going to be getting with your purchase of the door sills, next to the appropriately sized hi current relay.-on the right.



This is a very effective method to keep your car from being started with the key. As long as you hide the switch well. I have seen some guys use the Cigarette lighter as a switch. You push it in and it makes a ground connection, thereby tripping the relay allowing you to start your car. The lighter becomes your switch hidden in plain site.
__________

OPTION #2 is very similar to the above.... go back to image #9 and look at the back of the key cylinder again... you see the Large white wire with the black stripe on it? That is the wire then sends the "signal" to the starter, thusly tripping the solenoid, making the starter run, which in turn starts the car.
This wire can be found attached to the fuse block under the dash. It is a Brown, 3-Pin Connector on the right hand side just below the Yellow harness-- your SRS system--- DO NOT MESS WITH THE YELLOW CONNECTOR!!!

Cutting the White/Black wire and splicing the relay into it here does two things.. it will allow you to turn the car on, to the ACC or RUN position, but the car WILL NOT be able to start until you flip the switch and this line can be energized. The GREAT news about using this one is that once the car is started, it doesn't matter what position the relay/switch is in (preferably de-energized) until the next time you need to start your car.
You could even use a momentary, push button style, switch that would HAVE to be held in for the car to be able to start..once you released the button, the solenoid is de-energized and you are cruising in safety.

_______________

How, or if/why you choose to do this is up to you. I would rather spend the money and have an electronic security system installed in my car that has an optional Starter kill circuit designed into it.
But that is just IMO..
