i was trying to find a post regarding this a few months ago.

Was it ever decided where it is best to cut of, the fuel pump, starter motor etc?

Im going to beef up my security a bit and want to put a few hidden switches in the car to make the start up process harder. Any advice is much needed, it will surely be the best 50quid u could spend? Cheers luke

 

a good idea but do not tell ANYONE you have it or where the switch is - especially on the internet.

 

cheers ran but at the same time i need to know best places to put it. Even if people know about it it will still give me a bit of extra time to get the baseball bat!

 

I put mine on my 3 door so that if I moved the seat it would trip and I had to reset it each time I got into the car.

Literally the same thing as the normal cut off switch but with he inertia bit cut out of the loop and wired into th fuel pump wiring

On the Mondeo I've got anproper battery cut off with removable key fitted

I'm also looking at a way to rig up a spare central locking module to trip a switch somewhere

 

Dojj - thats a good idea with the seat mate. Hadnt of thought of that

 

i got a few quality ones i.ve now thought of!

 

pm me then

 

relay on part of the circuit so the relay cant supply the power !

 

Depends on what car you have mate to a degree.

I always removed one of the HT leads on my cars whenever parked up. Dead easy to do and peace of mind for no cost at all

 

My car got broken into a few years ago at uni; steering column smashed open, crook lock removed, hot wired etc, but my little switched foxed them until the neighbours disturbed them!

Best fiver i ever spent!

Q - why did the little &*^%'s take my crook lock with them - as a weapon?


Tom

 

if we had a £5 switch on my mate nova at uni - that would have saved it. Heartbreaking watching them break into it and drive off on the cctv

 

Really is - like house burglary at that age when your motor is your equivalent/pride and joy! Boils your piss.

I disturbed two shits trying to have off with my golf a few months back, but by the time i was outside they were long gone. I couldn't sleep properly for weeks, and the slightest noise outside had me out of bed and veins pumping.

Tom

 

you had a hardon?

 

Could u explain that as though your talking to a 5yr old please

 

Yes - if you dont get stiff when someone breaks into your motor i would consult your GP.

Tom

EDIT: honest guv, i am telling the truth, just like that pikey girl from facebook with all the money and a thirst for supras!

 

It was skylines actually... If your going to take the piss at least get your facts right. Just so u dont look like a nob

 

Car security bloke told me YEARS ago to cut the earth not the live to the fuel pump

Basically they drop a wire from rear lights onto live of pump, turn on lights and drive away lol

My old rover used to have an inertia switch behind the centre console. If I left it parked in a dodgy area then just reached behind and flicked the switch up.

 

Quality bit of knowledge there mate, cheers for sharing. I dont wanna fit these switches if there easily byparsed so info like that is quality

 

I had one on my 1985 orion injection ghia in about 1989 lol, worked a treat with no alarm!

 

top of the range back then mate, apart from the rs's

 

Which won't help what so ever seen as there will be no ignition etc present, so it woulden't be just a case of getting power to the pump!

Plus it's as easy to make the earth as it is the live, I also would be surpirsed if it diden't blow the fuse or cause a fire as the pump would pull more power than the lights would!

Personally I would not touch the fuel pump wiring at all!

If you have a decent immobiliser then this will inhibit a circuit (Ideally two point immobilation) and then it will be two circuits.

yer got a clifford 600, but wont a few extras mate for piece of mind

 

I think I would err on the side of physical security, after all this could detter them to stop them even breaking into your car in the first place

i.e. disc lock, gear lever lock etc.


Martin

 

LOL, aint the car thief smashing the steering lock and getting it started from rear of barrel anyway? and car thiefs are really bothered about blowing your fuses?....

You HIDE the cut in the earth INSIDE car so that when they run wire it just dont start and they hopefully leave it and run off

The question was about switches wasnt it...

 

I totally agree with what your saying, it's just personally I wouldn't touch the fuel pump circuit at all, in the same way I don't think it's good practice for alarm systems to be spliced into the wiring for the circuit, bearing in mind the current draw it has and the potential destruction it can cause (Engine wise) should anything go wrong, plus if you have a decent alarm/immobiliser then this will already be doing the job for you!

Martin

 

i got disc lock too, tempted to get a ground anchor too but bang for buck a 5 quid switch surely wins hands down, although i know it doesnt stop them just towing it of

 

Martin im not sure what bit my alarm immobilises but say its use fuel pump, what area would i be looking at immobilising, starter?ignition? Anywhere specific?

 

Most car alarm installers cut feeds at the ignition switch,then blend into the existing wiring.

Not sure what car you've got but I'm assuming its got an ecu etc then look at where the ecu is powered or earthed from and put your break in there,pull the plug to the ecu then solder in any connections,heat shrink them in properly so you don't have any future wiring issues with water ingress etc.
I say the key to any good immobiliser is making it look factory,not drawing attention with a big box with a toggle switch on it.

I'd break the wires for ecu,fuel starter and send them into a relay with 3 x normally closed contacts in a reasonably accessible location,then,I'd wire in an identical relay holder next to it,these wires don't need to do anything,put them under the dash etc then just remove the relay and swap to the dummy set of wires when you leave the car somewhere conspicuous,take about 5 seconds in total and baffle 90% of TWOCERS!!!!

 

As for running the fuel pump off the light circuit it works just fine,does no harm to the wiring at all,especially the period of time you need it on for.

 

You don't want to splice into the circuit by the switch else the thief can simply circumvent it! But yes typical circuits are the ignition and starter, if you immobiise the ignition circuit then the ECU does not have power anyway, do not confuse this with LT/HT ignition!

However bear in mind the age of the wiring of these cars (Cosworth isn't it?) when doing any work.

my RS1600i was saved with a kill switch that you had to open the boot to flick. Was quite cool actually and was fuel pump earth.

I got pissed off after a while and ran the cables into the front with bright red cables - when I was 20 this seemed a good thing to do - luckily no would be car thieve struck again and wondered if it might help the car start.

 

I fitted alarms ect before changing jobs

There is alot of things people dont know ..... alot of companys cut the starter which is 100% wrong as all thats needed is a quick bump start, So this also inc kill switches on the starter wire, Best to also stay away from clifford as we done little playing and was shocked on how easy they were to get past

On all my own cars i have just fitted a nice simple alarm EG one that covers all doors, boot & bonnet, also glass tamper inc a one cut on either ignition or fuel

Then extra things depending on car like a good immobliser with 2 cuts fuel & ignition

Then one step more is kill switch on say the coil (but please use correct gauge wire)

If you do a kill switch on the battery do the posative side as its not hard to get a ground cable bodged quick for the quick getaway

Hope some of this helps

 

?????

I'm not saying to do this that way,just that's exactly what most alarm/immobiliser firms do,they do it all around the area of the ignition switch,wherever's a convenient spot.

I'm saying to cut a wire related to the ecu directly,not via ign switch but physically inline as most thieves won't have the brains to know wiring diagrams,you could even just cut into say the crank sensor feed as it would t start then anyway.

If you do it in such a way as to look inconspicuous then it can be more effective than even an alarm based system as only you know what wires have been cut,rather than someone who has previous experience with an alarm firm using his knowledge instead of common wiring practices.

 

On my Cortina I wired a switch into the ballast resistor wire. The engine would turn over and fire up, but as soon as the starter motor was released the engine would die.

By the time they've twigged that it isn't going to start, they've made alot of noise and flattened the battery.

 

Would it be safe to cut into the ignition wires and just run a simple switch?

 

Fitted alarms are all very well but what happens when they break into your house and nab your keys? nice discreet switch somewhere will do the job!

 

yer its a cossie will all original loom apart from an uprated cooling loom with its on relay and powered direct from battery
