Fitting an immobilizer.

[supercass]

Anyone fitted an immobilizer (immobiliser) to their TR7. There is clear evidence that the criminal element are targeting older cars as they are easier to steal. I have an approved immobilizer to fit and I was speculating on interrupting the low tension circuit and the starter relay for this. Given that a minimum spec is usually 3 points I would interrupt the electrical supply to the fuel pump, except I still have the manual pump! Also even the starter <i>relay</i> wires seem somewhat heavy duty compared to the flimsy wires on the immobilizer. Any advice?
I am aware that even though this is an approved immobilizer it wont be accepted as such by my Insurance company unless fitted by an approved fitter (and serviced annually, I understand.) In fact my Insurance company do not make any adjustment to their charges in my case for fitting an immobilizer, I just want to help stop some joy rider making away with it! Thanks in anticipation. supercass

How about a battery cut out and take the key away with you?

Trouble is I'd have to mount it under the bonnet or do some chopping about on the dash. Not keen on the latter and if I did the former I know I'd just get lazy and not bother using it. supercass

You could always put it in the glovebox

I did fit immobilisers for a living at one point, realistically a hidden switch is just as effective.

My TR had a hidden switch that when activated the fuel pump was cut and the horn was activated if the ignition was turned on.

So the car would run for a short time until the carb had no more fuel but the horn would be howling its head off.

Mine is hidden up beside the bonnet/hood pull bracket.

It is a great hiding spot. It is automatically turned on after a short delay, when the ignition is turned off, & turned off by a button on the key fob. I have had trouble finding it myself, the couple of times the battery in the fob has gone flat.

<font color="teal"><b>The easiest way is to fit a switch under the dash out the way

or in full view marked as something totally different( like using a heated rear window switch if it is a convertible)

Remove the the wire at the + positive side of the coil get a wire run it from the positive wire to the switch

Then run a wire from the switch back to the positive side of the coil

the easiest way to do it is by running a twin core wire </b></font id="teal">

Hi,

I control the earth on my fuel pump relay via a switch, on the V8. Car will start up, but give it a boot full it will cut out, leaving the low life scum that stole it stranded and hopefully wondering ' what the hell ' and leave it there.

Cheers John

The low life caught me that way a couple of times. I was living on an island in Morton Bay, the entrance to Brisbane, & the scum targeted vehicles left in the ferry car park in the morning. They would drain the fuel tanks leaving people stuck.

I had a little Nissan Homer, one ton table top, with a fuel tank that was easy to get at the fuel tank drain plug. It would start & run about 50 yards on the contents of the carb. The bludgers usually threw the tank plugs off into the bush.

There was a story one day, that a couple of the islands dole bludgers had been found badly beaten, & had to be flown to hospital in town. The fuel stealing suddenly stopped just then, so I guess they'd found the right ones.

A hidden switch under the dash or a "converted" switch in plain sight has worked for me in the past.

As for siphoning fuel out of the 7's tank, I still have the plastic anti siphon cage at the end of the filler pipe, well it was still there when I replaced the tank. Some b'stard tried taking the fuel with a length garden hose pipe but couldn't get it Into the tank. The hose and filler cap were on the ground whe returning the car after leaving it for 15 minutes in a side street. The cap was probably worth more than the 5 gallons of fuel in the tank.

Ever since I converted my first dhc I have always connected the live feed for the fuel pump to the redundant hrw wire in the boot. Then it's just a simple task to fit a hrw switch to the switch panel and plug in the redundant plug for the hrw switch. Instant fuel pump cut off switch which is in keeping with the rest of the switch panel. Lights up when on and so obvious that a thief wouldn't think to look there.

Hi,

Yeah use HRW window switch too, but that's just between me and you so SSSHHHHH [:D] On my old 3.5 FHC added a second fog lamp switch. Guess been working on new cars for too long, they always switch the earth rather than a live, as more often than not a control unit is doing the switching and they don't like big loads [xx(]

The cooling fan override switch on my DHC once again controls the earth on the cooling fan relay via a standard A/C switch.

I've fitted a locating device to my car, very simple box of tricks (£30)that uses a prepay sim card. I just call it from my phone or any other authorised phone and it sends back it's co-ordinates and a link to google maps. It's very accurate. I won't say where it's hidden or how it's wired for obvious reasons, but you'd never find it with a casual look around.
Think my next move may also be some kind of immobiliser.

Bit of a shameless plug as I'm selling some trackers on Ebay that we used to fit to cars that are financed. The finance company that require them to be fitted have changed the supplier so I'm just selling the stock. They work well and recovered a Seat Leon and a Mini last year when the customer decided not to pay.
