Do you have an alarm, or are you attempting to do this with the factory keyless entry?  If factory keyless,  I can make something work with a few relays. 

If you press lock twice, does it not honk the horn?

Two answers:  1) Locate the alarm's siren OR the siren wires at the factory alarm 1 of these wires will either go pos or neg when the siren sounds. Then find one  (probably of two, both the same colour -yellow?) which goes  probably pos to run your indicators when you arm or disarm the alarm.  If the siren has a pos lead, join to one of the indicator wires then  immediately after that join,  break the indicator wire and insert a 2N54xx diode with the band facing away from the alarm.  If the siren wire is neg,  same procedure but take the wire from the indicator to a relay terminal 86, ground to 85 and 30, siren output from 87. Except this probably won't work especially as the "factory alarm" is probably a Cobra Cat l which uses a speaker not a siren. In that case 2) Obtain a small siren or sounder, run the indicator wire to it's red and ground the black.  That's your answer.  Don't ask for any colours, We don't know.  It's down to you and a DMM.  Incidentally the last trick with the sounder or buzzer is what Cobra themselves used to do.

here's my idea, it requires the use of  single pole double throw relay, wired like this,

pin 30- connect one of the indicator wires to this teminal, (anyone it doesn't matter)

pin 87a- to the siren's positive,

pin 85- to ground

pin 86- to igntion and using the remaining indicator wire diode thes two inputs to this terminal

this way the siren will chirp via the output of the indicators, but the siren will not sound while the van is in motion and you are using the indicaors, or if you had to use the hazards in case of emergency, with the van off.

t&t. you are behind the learning curve here, look at what I already posted earlier.  N.B. If and it's a big if, both indicator output AND siren "going" lead are pos, relay not needed, just a diode.  Actually if siren were neg, and door locks were same you could do the same thing with the diode direction reversed. Except if it's a Cobra unit, in the UK, also supplied as dealer fit option to Nissan and Mitsubishi,  the siren is a speaker so you will need a separate sounder. Methinks this is either a Cat 2-1 add on or uses the factory remotes.  If its a 3198 Cobra, with it's own remotes it  will be dealer programmable to chirp.   If it utilises the car's remotes, it won't be.

that looks good

not sure about  pin 86     it goes to ignition useing the other indicator wire  so do you want me to join a wire from the ign and the other indicator wire through a dioade and then into pin 86        is this what you mean    also were on the ing do i have to wire to   and is pin 87 not used thanks

pin 86 is connected via two three amp diodes bands facing towards the relay, the ignition and the spare indicator wire is connected to the other side of the diodes. pin 87 remain unused. Howie the way you described will work yes, but in the event he had to use the hazards in a case of emergency with every blink of the hazards the siren would also sound, the method i gave would prevent the sounding of the siren at any given time with the indicators in use, the only time the chirps will be generated would be when the alarm remote is used. Cheers

Relay NOT needed, t&t, diode placed where I said will block feedback from indicators/hazards, indicator feed more than powerful (current handling) to run siren or extra sounder. If the alarm siren has a plug in front, then it's a Cobra and is a speaker not a siren you will need the extra sounder.

i just thought this over, discard the indicator to pin 86 thiought, just carry the ignition feed to this terminal, no diode needed,

howie that system he has is factory, he would therefore be using an aftermarket siren, there will be none present in the vehicle, that indicator wire you are referring to would actually be the vehicle's actual indicator and not an alarm's output to indicator wire, get where i'm going,

Yes but not factory installed, it never is in the UK, at least not on far east vehicles, also in Ireland they have or had a lot of grey imports. If it's official the alarm is dealer installed with OEM type plugs, the leading manufacturer would be Cobra, this would either be with it's own remotes or an add on both Cat 2-1, i.e. factory transponder imobiliser with bat back-up siren etc.etc. Or controlled via the factory key fobs. Either way there has to be an indicator wire coming from the alarm's ECU. This will be either pos or neg going.  We don't know any of this so don't make assumpyions. I am because I've seen them before on Toyota (Fujitsu), Nissan, Mits and Daewoo (all Cobra). They are all installed at importer or dealer level. The control units are usually behind the glovebox or high up on the kick panels. The reason I'm plumping for Cobra is the fact they handle most of the dealer fit stuff here for imports, also their sirens are speakers not sirens. Don't DEI make a couple ,like that on the old Con 450 amongst others.? Unfortunately this person either can't be bothered or doesn't know how to tell us, so why are we hacking at each other? P.S The indicator line + sounder + diode routine works a treat, I've even done it on a Lexus!

lads thanks for your imput i was not near a computer in 2 days

howie were do you think the alarm is fitted is it at the drivers side or the pas side 

do i need a relay and diodes

the 2 wires i found are white near the fuse box they are + when you lock the car but not + when ou open the car ( disarm)

i have a print out of the 2 answers you gave me before should i gowith 1st or 2nd ans

thanks again lads
