1999 Dodge Grand Caravan, Viper 5902

I am having a viper 5902 installed by best buy, I work there so I get a 20% discount on labor. I was wondering if my Dodge Grand Caravan 99 needs a bypass module and if the wiring diagram is different the the standard Caravan. Also is there a way to wire the defrost up to the unit so I can activate rear defrost with the remote and regular defrost. Let me know if there is anything else that will help, thanksViper 5902 - Ordered

no the wiring is not different from the two. does not need a bypass. and the viper should have a dedicated output for defroster

how difficult is it to do myself? does it require a bitwriter to setup? I do not want to screw up my car, but yet I am willing to learn how to do stuff on my car too. I got the alarm for 200, I work for Best buy, and I can order viper stuff discounted like crazy!! Is it simply tapping into the wires listed on the diagram, like cutting a space in the coating and then hooking the wire to it? if thats the case I may do it myself, the only thing is the agreement for getting it so cheap says you have to have it professionally installed, so I am not sureViper 5902 - Ordered

also, is there a way to have leds hooked up to the battery, and have the ability to activate using the aux remote button on the unit, cause that would be kick ass, lolViper 5902 - Ordered

I have a question, why would a person use a DMM if you have the battery unpugged, wouldn't there be no voltage to read, or does it read the resistance of the wire. I noticed in the wiring diagram for my dodge 99 grand caravan it has 1 wire for the door locks and requires a resistor for the other wires connected to it, and some kind of relay, where can I pick up relays, and how would I set up the resistors? I may just have them do it cause I would hate to ruin my electrical system and not have a car, but I would love to learn how to do this on my own and have the ability to maybe do other systems for people. How much are multimeters and where can I get one, I mean if that is getting close to the cost of installation I might as well have a best buy do it for me. its 199.99 plus a 20% discount, so 159.99, but then they always add on crap to make it go up, they usually say, it took 3 hours longer so we have to charge you an extra 19.99 for ever 30 minutes.Viper 5902 - Ordered

also on top of that, how hard is it to wire a window module in, the guy at Best Buy said it would take him like an extra 2 hours to add that in, 90 bucks worth of install, and how do you tap into the aux ports on viper, also is there a way to adjust sensitivy of the shock sensor through the remote on the 5902?Viper 5902 - Ordered

you can get the relays at best buy they have them in the install bay.  That van is not difficult to do r/s on.  The worst part was getting the door lock wire.  If you look at the bottom of the bcm it's the plug on the left.  I unbolted the unit so i could lift it up a little bit and disconnect that plug to get at the wire.  If I recall correctly there are 2 wires that are close to the same color as what is listed as the door lock wire.  Make sure you test it and verify.   5902 should come with a 451m which is dei's doorlock relay(2 in 1).  You will have to solder in a resistor of the correct value for lock and unlock.
