97 jeep grand cherokee, viper 791xv

I just installed a dei starter and 455t in my '97 grand.  This was my first install and it honestly took me less than 2 hours total.  Most of the wires you need are right under the steering column.  The only 2 issues (minor) that I have/had was that I couldn't find the door pinswitch wire in the drivers kickpanel (so, I wired up the included one instead).  And, the automatic lock/unlock doesn't work, because I believe this is tied into the neutral safety switch that I just grounded (The remote lock/unlock works It just won't unlock automatically when returned to the park position).  When the weather gets warmer I will fish a wire to the tranny.  I am running it tachless and it works flawlessly but hooking it up to the coil wont be to much more work if needed.  There is enough room to manuever to under the dash to solder all the wires (which I did).  Also if you remove the 2 screws holding the factory plug I will give you more room as well for the 2 wire 455t install.  I installed the unit under the steering column after cutting out some of the foam but I probablly wouldn't recomend this spot for an alarm because it would be the first place a thief would look.  Their "might" be enough room behind the stereo and heating controls but Im not sure how muh better this would be.

my car doorlocks didn't work after i first tryed it but the remote start worked.. but after 5-10mins, it doesn't start with the remote or key.. i didn't wire the CCD BUS wires on the module.

It sounds like your connector for the sensors is bad. Do you have another alarm that you can test the sensor in?
