viper 5902 vs 5904

Can someone please tell me the difference in the Viper 5902 and 5904 besides the color of the remote? Also I have a 2007 Chevy Silverado Crew Cab (not classic). What extra module will I need in order to install this alarm in my truck. Thanks guys.

The truck has PK3+ ignition immobilizer and difficult door locks.  Save

yourself some headaches and get the DLPK bypass module.  It does a lot forthe money.  Online price is as low as $30, IMO, best bang for the buck.  Here is a link  :  http://www.xpresskit.com/product.aspx?productid=122

Soldering is fun!

they are essentially the same but the 5904 is the newer generation of it.  They changed a few of the harnesses but they install the same way.  I have used the flcan with the extra ring on this vehicle without issue.  I have even run it d2d between the vipers I install and the flcans.   It's worked great for me.  Without the extra ring for the transponder there is a little more standby current draw.  If it was my car I would feel more comfortable with the least amount of current draw as possible.  you can check out the install diagram for the flcan at flash-it dot com.   I also agree with kreg, as far as a cost effective bypass the DLPK is a good choice .Advanced
