OK,

I did a search on illuminated entry on the site, and read some posts, but they dont really apply to my situation.  I have a 1996 Dodge Ram, and a Patriot alarm system.  I dont know what model or anything, it was on the truck when i got it used.  My dad also has the same brand of alarm......possible a different model, and his has illuminated entry.

I have opened the alarm box under the dash, and I dont remember seeing anything that i needed to be hooked up so that the illuminated entry would work.  So i am guessing my alarm doesnt have the feature.  Someone else suggested that it may have an AUX OUT that keeps things on for so long that i could hook up.  So....if i have to add it....what exactly do i need to get to make it work?  I know i need a relay....but what kind, do i get it at radio shack?  I saw on this site the page that showed the relay and what needs to be hooked up to what...but i still dont know what kind to get if i have to purchase one.  Is this a fairly easy mod to make??

Thanks for any info!!

You said you checked the unit for outputs, I am not familiar with that brand but i know that DEI systems label that output as domelight supervision. You may need to use a relay to add this feture. Most security systems will use a negative output with between a 200ma to 500ma range. I would suggest using a standard automotive SPDT relay found in any auto parts store. If your system has a selectable input for this function you can probably get away witout it.
Good Luck!

The reason you are not familiar with this alarm system is because the manf no longer exists, as far as i know.  The date tag inside the alarm says december 1995....so...its old.  Anyway, i will open the box later today, and then post what things are in there, and maybe somone can point me in a more narrowed direction once you know what is there to work with.

Thanks for your help!

OK,

I got the box out and looked at it.  This is the cover of the box i have, and it has a list of all the stuff.  All of the wires are hooked up except a couple.

+12V DC Power
+Flashing Light
+Siren Output
-Ground CHassis
-Shock Sensor Input
-500mA Starter Kill Output
-500mA trunk Release output
+LED Output
-Valet Input

Then there are these three that are separate.
-Anti theft trigger input
-500mA Door unlock output
-500mA Door lock output

Notice:   -  and + in the list.

So, now what?  There is nothing for illuminated entry....so how do i hook this deal up so that the dome lights stay on for 30-60 secs or until i turn on the ignition??

Also, i was reading on this page that the relay for illuminated entry is hooked up like this...blah blah blah....but it says in there IF you have an output (30-60 sec)...then its hooked up like this.  I DO NOT have an output with that duration apparantly.  So, how am i going to go about adding this illuminated entry feature.

Well since it is obvious there is no illuminated entry output, there is an alternative. You can purchase a DEI 528T Plulse timer relay which will convert a momentary + or - pulse(unlock output) into a timed relay driven output. You can purchase this item for about $20. Here is a link that I found:

https://www.radiomancaraudio.com/detail.asp?PRODUCT_ID=DE528T

You will want to use a diode to ensure this works only with the keyless and not every time you unlock the door. If you have wiring Q's I am sure I could help.

Awesome.

I KNEW there was a way to do this.  Yes, i will need some help most likely.  The first questions i can come up with are where do i hook that timer relay to, and also, what kind of diode and where does it go?  Will it be as easy as splicing it into one of my existing alarm wires?

Also,

Is this relay going to allow operation such that

-the lights will come on and stay on ONLY when i DISARM my vehicle?

-the lights will go out BEFORE the time is up if i turn the ignition ON?

Yes, it can be designed so the lights will go out when you turn the ignition on, and yes they will only stay on when you disarm the vehicle. I can draw up a schematic for you to follow.

This is a pretty creud schematic but it gets the basic idea across. Since your truck should have 5 wire licking system, you won't need to diode isolate. This is assuming it is a five wire system and relays or a 451m was used for locks. posted_image

I wasn't able to find an installation guide for the 528T so the info i am going of of may be unreliable. this is something you would have to double check after you ordered the part.

Wow...a schematic would be great!  I will get that part!!

Thats a fine looking schematic....i see exactly what to do.  However, that is a relay on the bottom, correct?  Is that something i am going to need to purchase or what?  Sorry...im kinda unfamiliar with any extras i might need.  Thanks again for your help!

oh dam.....OK, i just now reread your post with the schematic.  That relay is the one under the dash that works the locks.  I don't know if its a 451m, but there is a relay there, because i felt it yesterday to make sure it was also clicking when you disarmed the vehicle.

The relay in the schematic is actually an extra one needed to shut the domelight of when you turn on your ignition. It is a standard SPDT automotive relay. You can usually pick these up in an auto parts store for a few bucks. The relay you already have under the dash would be the lock wire relay and is probably the 451m.

OK,

So i just need to pick up that extra relay and hook it to the yellow wire on the 528t.  The 12v ignition and the grounds i can just tap into off of the alarm box right??  That way it is an easy hookup.

And nothing needs to be done with the 451m relay right?  I ought to be able to just splice into any of the needed wires, directly off of the alarm box.  That would be best cause there is ample room and i can keep everything together.

Your best bet to access the wiring is going to be at the ignition harness. You will find a group of heavy guage (12 guage or so) wires leading down from the column. Use the red or pink/black wire for your +12v, and the dark blue for you +Ign. If you don't feel comfortable doing this then the appropriate connections in the fuse box will suffice.

**VERY IMPPORTANT** Fuse these wires close to the connection to protect the circuit.

you can tap into the unlock wire at the brain without a problem.

There is plenty of metal in the underdash which will give you a good ground. just use a circular crimp on connector to attach to the metal. use a star washer in between if you have one.

Well,

See when they installed my other alarm, just from looking at it, the 12v and the ignition wires already have heavy gauge and fuses in them.  I dont want to tap the same wire twice if i dont have to. I figured it would be OK since the wire to the ignition harness from the alarm brain is pretty short, and a heavy gauge, so i figured it would be OK, just to tap on into that one.  The reason i was asking if this is OK is because these wires have some gaps in them that are not taped up and provide easy access.  The harness itself is all sealed up with tape and it would be quite a pain to get to.  Plus, i wont have to add ANOTHER fuse, because the wire from teh brain is already fused. 

Comments???

I want my dome light, tail, parking, and maybe fog lights to come on and remain lighted.  These i was also hoping to get at from the brain wires.

there is no problem tapping into these wires that have already accessed the ign and 12v, just make sure the existing fuses are between the tap location and the ign harness. Sounds good!

OH,

OK, this is kinda gay, but kinda cool.  How do you make the domelight go out slowly, like on the camaro......where the light kinda dims out and then turns off?  Its super gay, but it adds a cool factor to it.

OK,

I hooked up the relay and the 528T exactly as per the diagram.  I cannot find the dome light wire, so i dont know if it really works or not.  But when you unlock the doors with the remote, the 528T clicks, which is good.  However, even after sitting for some time, it does not click again.  It has to click once to keep the lights on and then once to turn them off right?  There is only one click.  The relay clicks when you turn on the ignition, so i guess thats good, it also clicks when you turn off the ignition.  The 528T kinda worries me though.

OK,

I found my dome light wire.  The deal is all hooked up like the diagram says, however, the dome lights are NOT staying on.  When i unlock the door, they ARE flashing on and off real quick, but they are not remaining on.  So something is not quite right and i dont know enough about relayrs to see what it is.
