Cobra Alarm Wiring Diagram

[Nomal1st]

Hello, Good Evening and welcome

 

Could someone please point me in the direction of a wiring diagram for the standard fit Cobra alarm in the S1 Elise.

I'm after installing central locking to the mota, but after a days frustration, I have given up electrically testing the terminal plug on the control box of the alarm for a pulse negative signal on operation. Is it possible to add c/locking motors to the Cobra alarm? I notice on the back of the box is a "module" socket. Would I really have to buy an external control unit just for this? If so, where could I look at one online?

 

Cheers Lads

Hey its your lucky day ! Get yourself down to Maplin and buy the 4 door remote central locking kit. Comes with 4 motors, loom, black box of electrics and bits of metal work. Only costs £21.99. I fitted this to my S1. It has the cobra alarm with the tadpole style key fobs. I dont have the wiring diagram at the moment. Its on my other computer which I wont have access to till next week. Basically you attach the 12V cable of the loom to your battery and the black to the ground. Then you take the white and the brown cables to the cobra box. There are 2 pins these attach to and thats it !! Simple. I'll let you know next week which pins to use. Not bad for £22 eh !

Cheers for the Maplin info, it's exactly something along tho lines I intend to fit, just wanted to make sure it was possible to get the Cobra 6422 alarm (Yeh, black two button P-shaped remote) to control the locking before I fit it, else it would be pointless and I'd rather just do it by hand. If you could provide the wiring diagram so I could locate the Cobra central locking control wires, that'd be spot on! I shall wait to hear from you

Oh.... JUST thought! you are more then likely talking about the two un-used pins on the back of the Cobra box, after testing so many combination of wires on the main plug, I'd had enough and guessed the two pins I think you're talking about were just for an LED or external sensor, as they didn't seem worth testing marked "Y" or something like that I couldn't be arsed.. it was a long day, so it could be them

Will have the details after this weekend. It will all work as you have the same alarm. Go buy the kit, its a pretty easy job too. There were a fair few empty pins on my alarm but I will let you know which 2 to use. So good having remote central locking on the elise. Anyone that says on the extra weight should be shot. They weigh virtually nothing and are a pleasure to use especially if its raining!

 

Only thing to watch is that once you lock the car with the fob, the key will not be able to open the door. This is because the remote lock pulls on a pin in the door lock which de-activates it. So if you leave the car and the battery goes dead, you cant get into the car. Only way in then is to release the back of the roof and slowly disasemble the roof so that you can climb in. Even if you are in the car and try to pull the door handle, the door will still not open because the remote lock has disabbled the actual door mechanism. Sounds really bad but has never caused me an issue. If you are going to leave the car for a long time and think the battery might go dead, just lock it with your key and dont arm the alarm. The imobiliser will kick in on its own after 30 seconds so its not a problem.

Aye, like I say I spent the day (Saturday I think) dismantling the car and tryin to crack the central locking thing (I've only had it a week LOL and the no RCL thing is gash) and as you say I found on stripping the door to bits it would be possible! by making linkage to operate the door mechanism not the handle/lock linkage as on most cars, and with the door open, using a screwdriver to "close" the lock I explored all eventualities like you say, if the battery went flat you're screwed, I have a hardtop on mine most'a the time so that buggers me with breakin in via the roof I think I will run a hidden spare pair of control wires externally so I could hook up a temporary 12V supply and like a master criminal I would be in in seconds

 

Last night I quickly tested one of the two sets of pins with what seemed to be a blanked off wire... so stripped 10 mm off the end to test it on operation..and laughed to myself as it was a VERY tiny co-axiel cable, so, more then likely the aerial to the alarm! Haha, as a sparky, I felt somewhat daft

 

There is another two pins on the other side with some sorta of variable rotary control next to it marked VOL. It can hardly be the volume control for the siren! So I guessed it was the sensitivity of the ultra-sonic sensor or something similar. I think I'll just wait for your plans

hey,

 

Sorry for the delay. Here is the wiring diagram. I forgot you also have 2 earths as well and the lock and unlock wires. Its in Powerpoint.

 

Any queries, give me a shout !

Hey Piooly.

 

Much appreciated for the plans. While you weren't able to lay your hands on them, I quite stupidly contacted Cobra and asked them a similar thing and knock me sideways with a not so small anvil!! Not only did I NOT get a TIMEWASTING SH*T generic, totally irrelevant reply after 6 weeks, I got a personalised reply, from a HUMAN who even understood the query! and after a few hours had plans in .pdf Emailed to me! So after weeks of looking into this I now have a collection of some interesting stuff to any techo geeks, such as a computer drawn outline of the Elise showing where everything is located and a breakdown of all related electrics

This alarm can do so much more then 99% of people realise. It can control the central locking as you rightful said, can control the courtesy light for when you unlock the car, and I believe is even has a remote auxiliary control via the up-until now somewhat pointless B button

 

Oh the joys. LOL.

[Mish]

This looks like a good idea, how heavy is all the gubbins you need ?

Weight !! each lock thingy is about as much as a Mars bar. Do it. You wont notice the weight at all and its a god send once fitted!!

Hi, Sounds like you did have a hard time. I rang Cobra, asked to speak to there techincal department and spoke to a guy who told me there and then which pins to use. Took minutes. Oh well. The PDF then sent you would be of interest. Could you maybe email it to me? Would love to add a few more features to the elise.thanks.Oly.

Heyup. It’s a godsend, and as much as I appreciate the Elise is stripped and things such as power steering, ABS (or even a brake servo!) and E/W would ruin a true sports car, C/Locking would be nice! The stuff needed to run it, as Oly says, weighs as much as a shoe! So unless you take yours off and put them on the floor before you drive, don't worry about the extra weight In the month I've owned the car, the only time the roof has been on was on the drive home from Lincoln to Lowestoft LOL so I haven't really made a lot of use of the funky locking, but it should pay dividends in the winter once the hard top is on for good One gay thing is tho, coz'a how the Cobra 6422 automatically passively arms itself, I find myself walking away from the car after a minute or so, "locking" it as I do, to come back and find the doors open and the alarm off as all I've done when I walked away was un-armed the immobiliser which gave me the same two flashing hazard lights as I get on locking, so Grrr

Alrighty. Think you must have mis-read my bit Bud, was sayin how easy it was getting useful info from Cobra and that's what I was surprised about. I will send you a handful of .PDF's I have once I’ve got a mo. Some relate to the 8100 series, but in principle most features should relate to the 6244. I've only made use off the remote locking pins a.t.m., however have plans to bring the ignition once I've found out how the B button activates auxiliary devices, that way I'll be able to do away with the key altogether and have everything controlled via a CAT 1 alarm and start button Still working on that tho and waiting for someone from Cobra to get back to me about wiring up an auxiliary component as I can't get the B button to do anything other then disable the hyper-frequency sensor, which I feel is a secondary function of this button
