97 jeep grand cherokee, viper 791xv

yeah i have a solderin iron, a volt meter.. i should solder every wire?

where should i hide the unit.. whats the worst that can happen if do something wrong?

can it be that bad? how should i tap into the 12volts?

anybody?

wow, if you don't know whether or not you should be soldering or "twisting -n- taping" then you should probably just buck up and pay the shop to do it. i apprenticed for a year under a great installer before i attempted my first alarm and did a bunch of alarms before i did my first remote start. the worst that can happen during the install is:

- kill or smoke the factory computer

- deploy an airbag or two

- start an electrical fire

- etc.

and i can tell ya from experience that you are never completely done with an alarm install. here is the way i explain it to my customers. this isn't like a radio installation where if it doesn't go as planned then you don't have music for a couple of days until you get it fixed. this unit has complete control over your entire vehicle (ie. the starter, the locks, the parking lights, and door triggers). if you do something wrong then you are increasing your risk of becoming stranded somewhere at the least opportune time. when you couple that with limited experience of alarm backgrounds and troubleshooting skills AND a twist and tape alarm install you are asking for huge trouble. no offense but not everyone is qualified to DIY.

I'm no pro, but the first thing I did was find each wire: constant 12volts, door trigger, brake, park lights and so on. I used t-taps. I didn't cut any wires except the starter wire. It took me a few days to do this. So take your time, it could be done. After I found all of the wires I needed, I sat my alarm brain under dash very close to the top. Then I pulled each wire to its location, not making any connections at this time. Just make sure you have every wire you need where it should be. I used t-taps on all the vehicle wires and the alarm wire I cramped connectors to them. When I made my connections all I had to do is slide the connectors into the t-tap. The very last wire I connected was the starter wire because you have to cut that wire. Remember this took me several weeks because I didn't work on it everyday. And this was my very first install. 791xv.  Good Luck

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?
