How to fit a kill switch?
Hi everyone,
Due to my car having been broken into once before, and also because these cars are so ridiculously easy to steal, I'd like to fit a kill switch.
I've already sourced a switch that fits into the blank next to the heated seat button, and I'd like it to cut the connection from the battery to the ignition wires.
The question is, what wire do I cut into for that? A wiring diagram on what to do would be quite useful if anyone has one
Thanks

Soooooooooooooooooooooooooo
Immobilising the car 101.
Killing the power to the ignition switch? You’re going to want a relay in there; and it’s going to need to be quite a beefy one at that.
You could interrupt the fuel pump. However accidentally hitting the switch whilst driving could prove “interesting”
And do you really want to add more potential failure points to the 480 electrics?
I just use a good old fashioned, thatcham approved, stop lock pro. It’s a good visual deterrent, so in theory saves your doorlock/window/other method of entry, as they can easily see it’s not going to be a quick theft.

Re: How to fit a kill switch?
just use the switch to turn off/on the fuel pump supply, simples, even if you do swich off by accident on the move the car will just 'hesitate' whilst you relaise you have been a plonkerWillC9303 wrote: ↑Sat Jul 23, 2022 4:04 pmHi everyone,

on the SS1 I switched off /on the 12V supply to the coil same result, but you will need to remind your localgarage / MoT about it cos other wise they will curse you if swiatch it off when testing the lights . . . (ask me how i know

Re: How to fit a kill switch?
To be honest, these cars aren't really valued for thefts, at least as far as I know. I am however paranoid about the Audi going walkabout, so I have invested in a Disklok. Nothing will stop a determined thief, but as steering locks go, these are the best. The best you can do is make it look a pig to steal, and make it not worth the effort, these are pretty damn effective at it.

Re: How to fit a kill switch?
I'm with Jeff and Ben on this one I'm afraid, Will.
Although I appreciate your concerns especially having been broken into, that is something you'll never stop - smash a window and in you go. IN terms of the car actually being taken, which is what you are focused on, the 480 has never been viewed as a high theft risk car.
If, as they get rarer and (perhaps?) significantly more valuable, there may be more interest in stealing them, but I'd envisage that then as being an arranged "steal to order" situation. Those who do that will get past anything you do - let's face it, they bypass far more robust and complex systems in newer vehicles.
The alternative is the chancer,/yob/vandal who just thinks "that looks fun, I'll nick that, trash it and burn it". You're far more likely to deter such an opportunist with some very obvious physical obstacles (as per Jeff and Ben) to get round that might well make them just go elsewhere for a quicker easier target.
However, if you want to proceed down the kill switch line, I certainly wouldn't interfere with the ignition/battery wiring. You'd need a robust relay, robust wiring, and that switch is very lightweight as well to have all that running through it. Also the alarm system is connected to the ignition switch as well as the doors, so interfering with it could confuse that side of the CEM - I can envisage that breaking it could trigger the alarm when you lock the car.
Better is to interrupt the fuel pump circuit - that wiring runs from the pump under the back seat and forwards, you'd find it quite easily to intercept it.
BUT - I'm always wary of interfering any more than necessary with our aged, fragile and decaying 480 wiring looms...

Re: How to fit a kill switch?
Hi everyone, thanks for the helpful replies.
I think I’ll give it a miss then and invest in a steering lock instead.
I never really had in mind that people were going to steal it due to its residual value, as 480’s aren’t worth a whole lot right now. Plus, they’re rare enough (and in the case of mine) a distinctive enough colour to stick out like a sore thumb if it were to end up on eBay for parts or whatever. I had in mind joyriding yobs who burn cars out when they’re done with them like David mentioned. Saw a Dolly Sprint burnt out on Facebook recently that had been in the family since new.
As for the switch I’ve bought, I’d rather put it to use than return it to a blank. I was thinking a manual cutoff for the electric aerial, but does anyone have any other uses that they might have done?
Thanks
William

I have a switch in there to override the aerial...

Re: How to fit a kill switch?
Something I learned from my mate today with MX5s, he reckons its a good idea to take the fuel injection fuse out of the fuse box and take it with him, and then pop it back in when using. Sounds good, don't know how it would work with a Wedge mind...

just the same, no fuel means no engine power, a switch is eaiser and less obvious when parking up!!

although a lock only keeps an honest thief out.
back in 70's a guy on the same course as my dad had a car stolen (I think in Glasgow) so he chained one wheel of his next car to a lamp-post, so they nicked his car and left the wheel
