What do these wires do? Chinese Alarm System

I need info for wires:

9-Pin Harness
Green
VIolet
Blue/White

2-Pin Harness. the one that says electrical safety
Green
Orange

Wiring for my car:
2002 LANCER WIRING DIAGRAM
12 V (+) WHITE STEERING COLUMN
STARTER 1 (+) BLACK / YELLOW STEERING COLUMN
IGNITION 1 (+) BLACK/ WHITE STEERING COLUMN
ACCESSORY 1 (+) BLUE/BLACK STEERING COLUMN
HORN (-) YELLOW STEERING COLUMN
POWER LOCK (-) YELLOW DRIVER’S KICK
POWER UNLOCK (-) LIGHT GREEN DRIVER’S KICK

Now you will need to test the functions to make sure they work as expected.

Putting ground to negative inputs should trigger the function.
Negative outputs will test continuity to ground when activated. (Either a pulse or steady state)
Positive out puts will test +12v with DMM to ground.

Thank you lurch228 :) I've figured all of those wires. Man those chinese manuals are real difficult to understand. basically have to decipher them.

Only thing bothering me now is, on top left of the 1st pic, it's written function selection, what does that mean?

I'm a bit skeptical about these chinese alarm, do you think I should install the starter kill, or is it more trouble than benefit in the long run? If my remote stops working, can I use valet switch to dis-arm the alarm and still start my car when the starter kill is active?

So for the wiring of the starter kill, Orange goes to 85, ignition to 86, 30 to starter solenoid and 87a to key side of starter? Do I need a diode/resistor?

On 9-Pin Harness,
what does BLACK/ White(-), Channel 3 for?

Lastly, I want to keep the install neat, can I run 12v constant from ignition harness? Don't want to run wire from battery.

Once again, thank you for helping me lurch228

Should be the same as the programming button.

Mileage may vary on the longevity of the unit. You could get a good one that will last or not.
It has a sequence that will disable the alarm with the key and the valet switch. Don't know what it is for the Chinese models. Part of the instructions to disable it is in you last PIC.

If not and you want to have starter kill and not have to worry about getting stranded if it quits.

Orange should be GWA(Ground When Armed)You can test to make sure.
Do a "Basic Starter Kill" instead of a "Normally Open Starter Kill"!
Wire 86 to "IGN" and 87a to key side starter wire, 30 to starter motor side. 85 to orange, don't forget to diode across 85 and 86 band towards 86.

This way in the event the system dies you just have to pull the alarm plug that contains the orange wire to remove the coil ground from the relay to get going again.

For a alarm any wire that's the same size or bigger that is +12v will work, but for alarms the battery is the preferred method.

And as for the Domelight supervision, given that in the alarm, it has both positive and negative wires, do it mean that it has an inbuilt relay, thus I would connect negative domelight wire to negative door trigger in my car, or will I still need to use a relay to wire it up?

It should be able to drive the dome light direct from the alarm to door trigger.

It has an in built relay? I just don't want anything to go wrong with my install, being a newbie. That's why I'm trying to be safe by getting as much knowledge as possible.

For the starter interrupt, I saw on the page of starter interrupt, there is no diode for the install, here's the pic



Why you recommend I install a diode? Or is it not necessary?

Oh, or is the diode in built in the relay, across 87?

Diode is a must to avoid any surges. Diode is connected to 85 and 86 and is shown between 87 and 87a terminals in diagram.

Here is a pic of the chinese alarm i bought off ebay



It comes with a SPST(i think) relay for the starter interrupt and also a pre wired socket, would I need the diode?

For the domelight illumination, given that the alarm has both positive and negative wires coming out of it, means it has an onboard relay? So I connect one end to negative door trigger and one end to +12 volts DC? Or I use a SPDT Relay?

Buy a diode, 1N4004 and USE it. Any decent make would already have the diode built into the relay plug.
As for domelight supervision those two wires are simply alarm triggers from either a POS or NEG going switch.
When you shut the door does the dome light stay on, dims after a few seconds?
But when you lock all doors does it go out immediately?
If so like most Hondas and Toyotas you already have dome light supervision in the vehicle.

4 wire 4 pin is SPST relay. Still use a diode as it is recommended.

No the +12 doesn't get hooked up if you have a negative trigger. Only one wire is used depending on you trigger type. No relay should be needed as the unit should be capable of driving the dome internally.

Lurch means use the green wire not the violet and ignore the blue/white below.

As this is a Chinese alarm Connect the Green wire to the door trigger and verify that it works to turn on the domelight supervision with unlock and that alarm triggers when individual doors are opened.

Flushing out how it works and what each wire is, is a must with Chinese alarms and there poorly written and translated manuals.
As they don't always follow any one standard for the functions and how they are applied or use diodes for starter relays.

Ok given that the relay that comes with the alarm has the pre-wired socket, how do I install the diode? Should I solder?

Also let's say the relay already has a built in diode and I add one externally, does this cause a problem?

Solder with band to ignition input.
If there's already a diode you won't need another.

I bought this diode, I hope it will get the jobe done.
Diode

@howie, so how would I know if it already has a diode in or not? In case I install it and there is one already internally, what happens? Could you please also elaborate more on installing it?

Your diode is fine that's what is normally used.

It would show the diode symbol on the case diagram if it had one.
There usually always on the socket crimped with the wires in the terminals.

It will work the same whether there is 1 or 2. As long as they are installed the same way band towards the Ign.(+) which by convention should be labeled 86 on relay.

Solder to the wire, unless you can release the terminals from the socket with out damaging the tang that holds them in and solder to them then insert them back in. Both ways will work. It's a matter of preference which way you do it.

Howie i just checked the hot topic section for domelight thread you created....my car when i open the door the domelight lights up but when i close the door the domelight goes off after like 20-30 seconds...but if i close the door and lock it then the domelight switches off immediately....based on that and my alarm having a positive and negative domelight wires and my car diagram saying to use negative door trigger to connect domelight supervision, I wire negative domelight wire from alarm to negative door trigger of the car and don't use the positive domelight wire from the alarm? Also this means i dont need a relay for the domelight supervision? Thanks for helping :)

Yes to both.

Guys. so today I went to my local shop where the sell household electrical stuff, I saw they had wires listed as 1.0mm, 1.5mm, 2.5mm and so on. So I purchased the following:
5 metres of 2.5mm red wire
5 metres of 1.5mm black wire
5 metres of 1.5 mm red wire

There was a chart there and I remember for the 1.5mm it said max amp 16.

So can I use it when wiring the alarm like to extend siren/horn wire and also like connect 12v constant from alarm directly to battery? Is the wire that's used for household purpose also be used for our vehicle?

Here is a picture of the wires:



Thanks.

Yes that's fine, now return the 2.5 mm wire because you won't need it. By the way the length of wire on the alarm should have been sufficient to not need to buy any, just use the unused wiring!

Upon a quick conversion in google from mm to awg, turns out 1.5mm is 18 gauge, 2.5mm is 16 gauge. The reason I asked if i should use this type of wire that is intended for home electrical use is because on the alarm wire it's written 300v or 600v...etc on these wires nothing is written. Is there a difference between these wires and the ones that normally come with the alarm? i.e do they have difference characteristics/properties? Or they are all the same?

More conductor wires in automotive. If those wires are single core you can't use them in a car they'll break too easily.

Well on the receipt it's written flexible single core 1.5mm. So it's unusable?

Yes, don't why you bought them anyway, go to a Halfords they do smaller lengths of automotive wiring.
