My BA has a cobra cat 1 alarm and immobiliser, I think they were an optional extra from new, but if I get a new car as I think its a pretty good alarm i'd like to remove it and refit it to the new one, does anybody know how easy it is to remove it form the BA without having any issues using the car as normal afterwards, and refitting it to a new car easily without having any trouble with it?

Cheers

if it's a good alarm you may struggle

A lot of the alarms label the wires (which are all the same colour) then once fitted they remove the labels.

You may have to trace every wire, work out where they are going and then label them before removing

Also, if you fit it yourself then your insurance company may not give you a discount for having it installed....

Matt is SPOT ON as normal. Most factory fitted alarms use same-colour wiring to deliberately make it difficult to remove.

And no insurance company will give you a discount for fitting an alarm unless you have a certificate from a...certified fitter I tried "but i fitted it myself, it definitely works, could i not print a certificate off with my name on it?" and they said "probably, but it wouldn't be genuine, so you'd get found out and then your price goes back up, plus you'd have charges to pay for providing false details, with the possibilty of being taken to court" I said "I'll just pay the extra £50 per year"

Just get another alarm alex. The scorpion SA30 seems to be a popular choice on here.

x2. The price of getting the original or another Cat1 installed would easily be higher than any discount you get with it, and Cat1 or not, it won't stop someone smashing a window in to get in the car if they wanted to.

The SA30 is great - the only thing you may need to do is use a relay with the siren to stop it making odd popping noises now and then (possible interference from somewhere), it's something I did a while ago and Hughie has done the same as me now too and its fixed it for both of us

Yup highly recommend the SA30

And sloth is right, depending on where you ground the siren affects how/when it interferes grounded on the dizzy, it chirps quietly with the engine running. Grounded on the negative terminal, it pops when you switch on headlights, or put the heater on 4

A standard 30amp relay inline with the siren feed completely fixes it

Decent fobs too - look good and don't look like they are about to fall apart like a lot of them. Also the guy that sells the SA30 on eBay (it's the only thing he sells I think) is a great guy - if you have a problem or faulty part he'll get it sorted nice and quick. The alarm comes with a blue LED so I asked him for the spec so I could get a red one.... and he posted me a red one for free as well as giving me the spec

The alarm i've got is already a good one, i prosume its quite old but is still being fitted to cars now and has a lot of features, its a cobra one not sure if its factory fit or not?

Also I don't think I get any insurance discount for it anyway, the only options they ask is security features:
None
Engine Immobiliser
Tracker

The only reason I'm wanting to fit it is it is a good system and rather than getting rid with the car I could fit it to help protect the new one, if i was to label where the wires came from when removing would this be easier?

Cheers

If you're not bothered about the discount, then yeah... all you'd need to do is trace each wire and find out what it does, label it, and remove I guess.

If you're stripping the car anyway you might as well take it off - doesn't matter if it leaves the cars loom in a bit of a mess then. But if you're selling the car, you may need to make sure it still starts afterward

Like I say I don't think the insurance really give a discount for an alarm as those were the only options, so I'm happy just to take it out and fit it myself if it is easy enough, just to make the car more secure

i'm just gonna go ahead and use this topic a bit.
I have a ASN BAS-322 immobilser mounted in my car. I recently aquired the manual and wiring diagram. The immobiliser supports the following:
Battery + wire
Battery - wire
Fuel pump wire going in
Fuel pump wire proceeding out
Ignition wire
Starter motor wire going in
Starter motor wire proceeding out
Useless wire (not to be connected)
Siren wire connector on the mainboard (no wire)
Open central door locking wire
Close central door locking wire

While the wires aren't labeled, i have details on the soldering of the various wires so identifying them won't be a problem.

Q: Recently i'm having problems getting my BA started in the morning. While it does turn around and start after a couple of seconds, it isn't smooth. I'm personally thinking that it has something to do with the immobiliser controlling the signal to the fuel pump. Say i want to fix this, does this mean simply desoldering both Fuel Pump wires and connecting them to eachother thus closing the loop?

another Q: say i want to fit another alarm, of which i also have detailed wiring diagrams. Could i simply desolder everything on the old immobiliser and simply connect the new alarm onto those wires, ofcourse closing the loop of any wires i don't need (such as the Fuel Pump wiring)?

found my answers little bit of logical thinking helps.
