I've searched but the question I have is for a sedan instead of a two door. I was reading up on the door trigger wire to be tapped into the passenger side because it controls both sides, but what do you do when you have a sedan. Do you still tap into the passenger side for the trigger wire? If not, which door and wire do you tap into for the door trigger wire to control all doors.

 

Although you didn't bother to tell us anything other than you have a "sedan" (make & model would help), it depends on the vehicle.

Some vehicles have a common trigger for all 4 doors, and some have multiple triggers. The one with more than one, you'd use them all, and diode isolate each.

 

nevermind, i figured it out haha. it was on a honda civic 1997 sedan

 

fOR most Hondas/Acuras, the negative door trigger is the GREEN/RED wire, usually found near the driver side kick panel area. Remember that it's the one with only ONE silver marking, not two.

 

thanks, i just noticed that tapping into that wire, my dome supervision light does not work. where would you wire that too, the domelight supervision wire?

It has to be the passenger side wire. The driver's side wire is upstream of the domelight and the passenger side door.

The 01 and newer 4 doors require you to connect multiple wires and diode-isolate them. Any car that has individual door indicators on the gauge cluster has the same requirement and for the same reason.

You still haven't told us which alarm and you should be shot for that. DEI has two different wiring schemes for the dome light. One requires that you add a relay and the other has the relay built in and you just have to ground the black/white wire on the power door lock harness.

 

the alarm is viper alarm dei 350 hv

so i tried making the dome light supervision work by connecting it to the green/red wire with one silver marking and it is not working. do i have to wire it along with the door trigger wire and the dome light wire connect to the green/red wire?

 

Assuming you have the correct door trigger lead, [alarm triggers when any door is opened] you will need to use a relay to supply the ground to the green/red, use the dome light supervision lead, [H1/4 black/white] to control the relay, the 200mA neg.(-) output of the dome light supervision lead is not enough for the dome light, hopefully you have not damaged the output. 94

 

so if i use the black/white wire to control the relay, how do i wire all the other ports on the relay? i know that the black/white wire goes to port 85, the port 86 goes to a constant 12v source, but where does each of the 30 port, 87 port, and 87a port go or connect to?

 

i also tried to quickly connect the domelight wire to the door trigger wire i had hooked up but it was not enough to power the dome light so i need help to hook it through the relay like the manual says but i dont quite understand how it is hooked up

 

You want the relay to do the same thing as the door pins do, supply a ground to the light, so as you said " i know that the black/white wire goes to port 85, the port 86 goes to a constant 12v source, #30 will go to chassis ground and #87 will go to the dome light lead, [green/red] you can connect it along with the alarms door trigger lead, #87a is not used. 94

 

i will give that a try and see what happens

 

i tried that and it works but the domelight only flashes for a quick second then shuts off. what would be the problem then?

 

should i tap straight into the dome light wire source?

 

The door trigger lead, [green/red] is the "dome light wire source? again, if you have the right green/red.
Have you tried to see it opening any/all door triggers the alarm?

You can also test the relay and connections by just grounding to chassis the terminal on the relay that the black/white is connected to, [#85 I think you said], if the dome light stays on as long as you ground #85, it is a good bet the dome light supervision output, [H1/4 black/white] is damaged from connecting it directly to the dome light ground. 94

 

yeah, i have the right door trigger lead. the alarm gets triggered when i try opening each door.

I bet that will confuse him.

I would add, to the same place as the H1/8 green neg.(-) door trigger.

i tried wiring it up like the diagram above and that does the same thing as before, it just blinks for a second then shuts off.

i then tried grounding the 85, the black/white wire that goes from the alarm's brain to this port and grounded it, the dome light did not switch on when the alarm was disarmed

 

Don't ground the wire from the alarm, ground the terminal on the relay it goes to. 94

 

So I grounded the terminal on the relay that the black/white wire from the alarm is connected to, and disarming the alarm the domelight does not light up.

 

If the dome light does not come on as soon as you ground the terminal, [alarm does not even need to be connected] then you have something miswired.

Does the dome light work when you open the doors?
If so...
Check and make sure the relay is wired correctly.

You must have 12V+ constant, [hot at all times] on #85 or #86, [it makes no difference which one you use] the black/white goes on the opposite one, #85 and #86 are the two ends of the relays coil and as long as there is 12V+ on one side and a ground on the other side the relay will energize, it also makes no difference which one you switch, the pos.(+) or the neg.(-), in your case it is the neg.(-) that is switched, [black/white].
You must have a ground on #30 or #87 again it makes no difference which one you ground as long as the other one goes to the dome light ground, [green/red] the same place as the alarms door trigger lead goes to.
If that is all wired correctly then grounding the terminal that the black/white lead goes to ill energize the relay and turn on the dome light. 94

 

i rewired it to as you specified and when i ground the port that the black/white wire goes to, the dome light lights up whenever i arm and disarm the system. so if that is happening, what is the problem when i'm wiring everything correctly? cause when i rewire it back up like you said previously, the domelight just flashes a quick second when i disarm and shuts off. isn't it suppose to stay on for a while for the domelight supervision?
