Hello all car alarm experts!

The Elise comes with a Cobra 8186 cat 1 alarm as standard. This has the standard microwave sensor which goes off if somebody enters the car.

I was wondering how I'd go about changing the sensor for a dual zone one that warns people away when they get too close (like the Cliffords do)

Would something like this do the job and how would I go about wiring it in?

brown wire......switched earth
grey wire........external trigger
red ....live

you can pick these wires up at the main unit behind the panel next to the radio, or at the existing sensor wiring.
if you leave the original sensor plugged in connect the trigger wire to the blue/pink at the unit or door pin switch.

if you connect to the grey wire you can cancel the sensor with the small button on the handset.

Sorry, I'm not following you here.
I took a pic of my sensor yesterday and it appears to have 3 wires, black, blue and purple. (it's difficult to tell as it was dark when I took the pic so I've had to increase the contrast to be able to make them out)

I assume that these 3 wires are the switched earth, external trigger and live. I understand that the dual zone sensor has 4 wires, do I just need to unplug the original sensor, put the new one in its place, connecting the relevant wires and the extra one is the output for the warn away siren

Dude, why are you even bothering? You just like messing with stuff yeah? :D

Car is garaged at night surely? And it's not the sort of thing you'd take into town on a Sat night....

Yeah, it's garaged and rarely leaves my sight but yesterday a bloke at work caught 2 kids paying a bit too much interest to my car. When I checked the CCTV they were the same 2 kids that had nicked a motorbike from next door literally an hour beforehand (they nearly knocked me over at lunchtime as they sped away!)

And yeah, I do like messing with stuff too :D

LOL, got bored of cycling to work all of a sudden eh?

:D Can't say I blame you having that on the drive. I'd rather take an Elise to work than go by private jet.

Oi, I cycled today. I'll have you know I'm sat here in my shorts today (the benefit of having your own office ;))

Dynamat Extreme (lightweight stuff).

The standard touring pack sound deadening for the Elise is 35kg so I decided to add my own which is about 3kg, much better.
I've also got a quicksilver exhaust (10kg lighter than standard and 10x as loud!) so I'm still doing ok for weight saving.

By the time I add my amps and sub I should still be about 25kg lighter than a standard 111R Touring :)

as you look at the unit in the drawing wiring plug on the right(unit upside down) first wire left hand side is powered 12v, second(middle one ) is switched earth, and the far right is is your sensing wire. cobra supply the units ,the wiring is factory loom colours.

Cheers for that, makes things much easier :)

I've ordered the Microscan sensor as it had the Piezo buzzer as part of the package.

Do you know if it's possible to change the remote fob to a different one. It's just that I hate that stupid rubber bit that attaches the fob to the keyring.
