Car Alarm Help

In my 1991 Celica, i have a car alarm with keyless entry. Everything works perfectly, and the alarm goes off and everything, except that the alarm system isn't hooked up to the indicators. So when i unlock or lock, i get the "beep beep" but no flashes.
I would like to hook these lights up. I will look on the box and put my test light into each connection until i find the light one (one that flashes as i lock and unlock the car). Now, where do i run this to? I want both indicators to flash.
I think that if i run it to a part of the indicator that stays on constantly as you push the hazards or indicator, that it will then go through the "magic box" that turns a constant signal into flashes. If i do this, then the double flash might get converted into a single flash when it goes through the box.
am i making any sense? Where should I run the wire from the alarm to, and what sort of diode do i need? Can i just hook it up to the frond indicators and they will all work, or do i have to run seperate wires to each light (EG front back side).
Thanks alot
The alarm is a DEI Hornet, that's all i know. Everything was already installed when i got the car and i don't have a manual for it.

ok, here is what you do:
# go down to your local jaycar, and purchase 2 x 1N5404 diodes (cat no. ZR1014) and some wire if needed.
# from the small loom of wires running down your steering column there will be three wires that are for indicators (one left, one right, and one for both). These are usually green or green with a stripe of varying colour on Toyotas.
# with your test light, identify the two wires that flash for only ONE side each (NOT the one that flashes for both sides).
# connect one diode to each of those wires, making sure that the "stripe" side of the diode points towards the wire.
# with some wire connect each of the "non-stripe" ends of the diodes to the flashing output of your alarm.
PROBLEM SOLVED

Sweet! Your a legend!
So where do i find these wires? If i put my head where my feet usually go and look up then will i see them or do i need to take some panels off?
Thanks alot man, that is exactly what i wanted!

Hey, I love JayCar but it's over an hour from where i am. I rang up dick smith and they hav heaps of diodoes but don't use those model numbers that you said. What should i ask for when I go down there? The guy on the phone didn't seem to know much and said he couldn't tell me which one to get because he wasn't qualified or something. Thanks again witzl

Why don't you try connecting the leads to the wires that run from the hazzard switch, or don't Celica's have them. That switch should have connections for indicators on both sides of the vehicle in one spot and should be easy to get to. That's how I've done it in the past with other cars without problem.

My amazing tip of the day:
Do you have your boot/hatch wired in to the door-open input on your alarm too? If not, grab 3 diodes instead of just 2. If you run a wire from the pin that turns the boot/hatch light on to the alarm, chances are it will link your boot-open circuit to the door-open circuit and thus turn the main interior light on whenever you open the boot. A bit annoying. Even if your alarm has 2 door open wires, they might not be isolated (weren't on mine). Put a diode in line and you're away.
My other less amazing tip is... some weird stuff happened when I tapped the indicators initially. I can't remember exactly, but I must have either not used diodes, or tapped the hazard light circuit, or had the diodes back to front, or all of the above. Both indicators would come on whenever one came on.
After installing my alarm once, I went for a drive, and after a while realised I had magaed to wire the indicators back to front! Left was right and right was left. Funny, but potentially very dangerous!

and the reason witz recommended jaycar? 
I popped in there the other day incidentally, and the chick at the counter owned an s4 13b-t rotor with a t04 turbo.
I was impressed

Alright! All done and it works perfectly! It was soo easy too!
Anyway, i found on the alarm that there is a negative output for "channel 2" and "channel 3". does anybody know what this means. also there is "domelight" which is also negative. Does domelight put out power when the car has been unlocked but before it is started? If so then how can i wire it up to my interior light? Is channel 3 and 3 for when i push button 2 and 3 is for when i push both buttons together?
Thanks you guys are really smart!

A negative output normally means that when the alarm is activated or deactivated the connection shorts to earth. So you can link that connection to something such as a horn that requires an earth to activate. A positive output normally puts out 12 volts when the alarm is activated or deactivated. So you can send 12 volts to some other device such as central locking when the alarm is armed and/or disarmed. The domelight probably earths the domelight and/or one of the door switches to turn the interior light on (same as when you open the door, the light switch shorts to earth and turns on the interior light) when you deactivate the alarm. So you could walk up to your car, deactivate the alarm and have the doors unlock and the interior light come on. Hope this sort of makes sense and is od some help. Have you looked up the alarm on the internet to see if you can get some instructions ?

Siic, so do you think channel 2 and 3 are triggered when i press button 2 and both buttons respectively or would it be something else?
How could i wire up the domelight wire so that it triggers my interior light. where is the wire that i would have to patch it in to? I know how to do it all, i just need to know which wire it is? Where is it usually located or is there a standard wire color?
