What is the fastest area or best location to locate the electric fuel pump circuit control? does it have a relay or circuit fuse in the system, if so where can i locate it?
The makes are Toyota cars and jeep, the models are from 2004 till date, the others are mercendez benz cars and jeep,the models are also from 2004 to date
Most of the vehicles you mention will have fuses located in the fuse panel inside the cabin are under the hood in the power distribution center, this is also where you will find the fuel pump relay. Good Luck.
hello all, pls i would like to know if it is possible to disable the engine without making the steering in to manual, if possible how? because in the cause of stopping the engine, the steering changes to manual and becomes stiff and cannot be control, as this will likely lead to accident, there should be some measures to still keep the only the ignition switch on that will still make the steering controllable, when the engine is cut off, which circuit am i to look for for this to adapted to the systems?
You are in a very dangerous area. The power assist to the steering, and the brakes is provided by the rotating of the engine. If you stop the engine from turning, you will no longer have the assist that make steering easy. The brake system stores some of the energy from the engine to allow 2-3 stops before the assist is gone. At that point, the braking effort will become MUCH harder. Are you deliberately turning off the engine in an attempt to save fuel?
No it is to immobilise or stop the engine when the vehicle is stolen through a gps command systems via an immobilisation relay without causing accident.
If it were me, I would Have the remote relay do other things besides shutting off the engine.
1) They sell rpm limiters. An MSD 6AL is the first one that comes to mind. If you were to fit it with a 1,000 rpm limit, the car would have the advantage of a better ignition spark that should give an increase in power, mileage, and drivability. Until you remotely activate the rpm, then the engine would not rev any higher than 1,000 rpm. That is just above idle. The thief is not going to get anywhere like that.
2) Buy as loud of a siren as you can afford. Trigger the siren from the same relay.
3) Get a real loud horn, and tie it also to your relay.
How far do you think a thief is going to get with a siren and a horn blaring while he is just idling by. As soon as attention is drawn to him, he has to leave.
pls tell me more in simple and comprehensive terms what this rpm limiters is, what does it functions as, where can it be located?how i can adapt the immobilisation relay to it?
About the only rev limiter that would function at such a low rpm is made by Pertronix and could be set up by triggering a relay on the ground of the Rev limiter. You would trigger the ground of the relay with a signal sent by the gps or by use of a pager. A better way is by a company called Trillionn. you can see the system at this site . Hope this helps.
Try reading this site. It describes how to connect to your vehicle. Choose the lowest set of RPM plug in modules, and use your relay to activate the system.
G'day, Look up Silicon Chip in Australia. www.siliconchip.com.au/.
They have published, in past issues, an interupter circuit that would allow the engine to run for say 30 seconds then cut out. I could not be started for say 10 seconds then cut out again 30 secs later and so on. It is a security device/
You may also look up Jaycar http://www.jaycar.com.au/ and look for immobiliser kits in the auto section. Jaycar also have a couple of outlets in the US.
If you have all options, put the circuit as near to the power distribution area as possible. It should have a relay, and a pressure sensing switch to shut it off when there is no oil pressure. By pass the oil switch during starting. If it uses electricity, it needs fuse protection. Use a fuse, circuit breaker, or fusible link.
Int he back of the Haynes Manual (usual disclaimer) for each car is a set of wiring diagrams for each model. It will be found on those.
