led’s and car alarm

I am getting the viper 5902v and it has aux ports I guess. I want to be able to hook up some led's to be activated when I push the aux button on my remote that are placed under all the seats. I plan on buying a bunch of blue led's and hook them up to the battery. I was wondering what switch/box would allow me to send what ever signal out to a switch so that I could turn on led's with a remote button. Thanks for any help, also if anyone knows, does a dodge grand caravan 1999 need a bypass module for a viper 5902? My local car guy said probably now, but just want to see if anyone knows for sureViper 5902 - Ordered

all I need to know is what relay would work to switch the leds on, cause the alarm can send a 200ma voltage and be used to switch on a relay that will cause the led's to come on, any one know?Viper 5902 - Ordered

A standard 30A bosch relay will work.Kevin Pierson

how would I wire it to work, have a 12volt source go in one end, a ground for another pin, and then the aux line to one of them? is that correct, then when the aux line sends a charge it will allow the 12 volt source to give the led's electricity?Viper 5902 - Ordered

ok so I found that relay, if i get this Link will that be the right connector to hook to it? also I want to do like 50 led's on the drivers side, and 50 and the passenger side, how would you wire that to make sure eash blue led gets the correct 3.3 volts? should I do 3 with a resistor, or is there a way to not use resistors and just wire them in 12v series, and then hook the series together parallel? and then for the relay, there are 5 connections, im guessing that the plugs will be, 1 for 12v in, 12v out, the alarm input voltage, alarm output voltage going to ground? whats the middle prong for? any help would be awesome!!Viper 5902 - Ordered

ok, I learned how relays work, is this the relay required for my car, which says it needs a #775 part? HERE IS LINk, is this the same relay that will work with my leds, this one does not pass a current when no charge from alarm module is off, and when the alarm gives a charge then the relay allows the leds current? I coulnd't figure out what the difference between this one LINK HERE #2 is and the first link, is it just the allowed amperage? Thanks, if these questions are answered then I think I know how to do all the things now, just a matter of how to wire the LED's tooViper 5902 - Ordered

You want 100 3.3V 20mA LEDs. That's 6.6W = about 0.5A at 12V. So first guesstimate - a 30A relay should handle it. In fact, it might handle 60 such installations. How many in series? 3 x 3.3V = 9.9V 4 x 3.3V = 13.2V Some would just use 4 in series and no resistor. If max car voltage is 14.4V, that's 3.6V which is probably within LED tolerance. And at 12.4V (a typical non-charging real voltage?), that's 3.1V per LED. Others prefer the resistor..... So drop 3V @ 20mA = 150 Ohms @0.6W (R=V/I & P=VI or IxI/R). So 96x 3.3V 20mA LEDs and 32x 150 Ohm 1/4 or 1/2 Watt resistors connected 3 LEDs & 1 resistor per string. Each seat is 16 stings @ 20mA each = 0.32A per seat or 0.64 for both. Let's say 1A total current. (So not ~12W total.) You might want to double check the above and check against LED specs and tolerances - you might decide in a 180 Ohm resistor instead.....

thanks man, I am trying to figure out what relays will work for my car, I put a few links, my car says it needs either the 775 or 778 relays, will the ones from the link work?Viper 5902 - Ordered

I made up this diagram, will this work correctly, is there anything that I need to change? , if that doesnt work here is another link to it Picture Please let me know, if that works then I am all set pretty much for that partViper 5902 - Ordered
