I was thinking I'd do this to my car, it seems like a pretty easy, cheap and effective thing to do. i want to install a magnetic reed switch onto the ignition. I'll hide the switch under the carpet somewhere, and keep a magnet in the car, so I'll have to have the magnet over the switch before I can start the car.

I was reading http://www.6gc.net/forums/index.php?showtopic=16174 , and from what i gather:

Starter
This wire is used for remote start and for starter-kill, which is when the car won't start if the alarm is armed. The starter wire in a sixth generation Celica is black/white, and is located at the ignition harness. Like the ignition wires, it's a fairly thick wire.

I can make this work if I just put the reed switch inline with this black/white wire? Can someone tell me if this is right for the application i want? Also, will this allow me to have the car "on" as in electrical wise, so if the key is turned to 'ACC' or 'ON', without the engine started, can I still listen to music and everything, without the need for the magnet?

One more thing, if this is the right wire, where would I find this? The "ignition harness", is this just inside the steering column?

use a switch...what if the magnet loses its power laugh.gif

anyway you gotta hook it up between the black/white (starter) and the black/orange or just black (ignition)
so when you apply magnetic field to the switch the irons will line up connecting the two wires thus cranking the car...

edit: my bad you want to diable the starter, yea you are quite right just connect the magnetic reed somewhere between the starter wire...you will have to place the magnet over the switch and crank up the car, and if im not wrong you should be able to listen to musics and stuffs with the key to acc or on.

Haha. Well I figure I won't bother flicking the switch back when I'm done, and with the magnet, I wont need somewhere to mount it, I can just do it under the carpet somewhere. I'll keep a spare magnet in the car too tongue.gif

Also what I want to do is only use the magnet to enable starting the engine, not to actually start the engine, with this, would I just have the switch inline with the black/white wire?

Haha, well this is where this idea came from. I figured I'd get an immobiliser, but then I thought of this. I'll see how this goes though, if it doesn't work.. I'll reconnect everything the way it was and pretend it never happened. tongue.gif

Just out of interest, where in aus are you?

the easiest thing to do would be to just put in a 12v switch (hidden somewhere). Just use it to interupt the starter wire (when the switch is switched off).

The best place to get to the black/white wire is directly behind the radio, in a taped/loomed vertical wire harness. Just unwrap the loom, and it's in there. Splice in the wires that goes to the switch, mount the switch in the desired location, done. If you switch it off, the car will not start no matter what, it will just crank. Then flip the switch on to make it just like normal.

this would kinda be ideal if you're in a place where you think your car is gonna get stolen, or leaving it somewhere overnight, ect...

Ah, that makes it heaps easier to wire then. What I was thinking now, I'll just get a push button switch, one that doesn't stay in, and just have to push that down while I start the car over. Easier then holding a magnet over something. tongue.gif

Well I had a crack at this today, and I couldn't seem to find the right wire. Batman, would you have a picture of the wiring loom you mean? I took off the centre console, and I just tried to take the white/black wire that was in the horizontal loom at the very top:

IPB Image

But when i cut this, the started did cut out, but I kept hearing a buzzing sound from my engine bay.. When I reconnected the wire the buzzing stopped?

I'm not sure if I'm looking at the right loom, or if its even possible to do this now, maybe it's wired into my alarm?

To get to the loom you said Batman, do I need to actually take my radio out to get to it?

you are so close.

IPB Image

take the radio out, it's vertical to the left of it (yellow arrow)

the wire is thicker than the others, blk w/wt stripe or wt w/blk stripe, I can't remember.

Ah. I was looking at that loom, but it was so tightly bound up I wasn't bothered to do it at the time tongue.gif I guess I'll be having another shot now smile.gif

Ok I'm 99% sure thats the loom for my actual radio. Mine is a RHD, so I'm guessing you mean the loom to the left of it? I had a look at that. But it's fit snug in there very tight. I can't even get an inch of slack to have a look at it..

Where else can I pull this wire from?

So the passenger sidekick panel that's closest to the outside of the car?

Bah. Who'dve thought it'd be so hard for me to find one wire tongue.gif

ok, you have the wrong idea. if you are trying to do this to have a hidden switch, as in a kill switch which would keep the car from being started by a thief or ex wife (lol). what you really need to do is interrupt the ignition wire not the starter wire. this would be the wire that becomes hot when you turn the ignition to the position just before you engage the starter. this is best done with a relay of sufficient amperage to handle the current that the ignition system uses. just using a push button switch or reed switch is a sure path to a failure.

this wouldbe the black/yellow wire which you will find in the left kick panel area. this wire supplys power to the ecu.
