This question may have been answered already but I guess I am overlooking it. What do I need to do to my factory alarm in order to install an aftermarket alarm/remote start? Do I hook up the new alarm as if there is no factory alarm and just not use the factory remote? Disable it?(how?)Will I need any type of interface? Thanks for any help.

DEI part number on the interface module for your vehicle is 455T. It will allow you to control the factory alarm, door locks and more. The installation manual can be downloaded here

When I use this can I use all the features of my new alarm or will it bypass it and use only the factory alarm? I have installed stereos, amps, keyless entry systems ect. before but not with a factory alarm. I work at a bodyshop and know how much trouble it is to trace a wiring problem. Thanks for you help. i have the 455t ordered now.

This interface allows your after market system to control what is in the vehicle from the factory. It is an add on and will not affect any feature of the after market system you are adding. All of the features your system has will work fine.

GREAT. Thanks for your help. Hope to get it put in next weekend. The remote start part isn't too hard I hope.

If this goes ok I may tr it on my truck. I have a Ford Ranger with the coded key. I think I saw something like the 455T for it. This will all work out great because we have only one remote for the jeep and truck. Now we can both have a remote. Thanks guys for all your help. I have gotten a lot of info from this forum. Thanks again.

Make another post when you're ready to do that ford ranger, you may have to do some extra work concerning the door triggers on that one.

Looked at the manual for the alarm this weekend. Confused now but still gonna do it (I think). The onE I have has a dome light supervision output, factory alarm disarm output and factory alarm rearm output. It also has a (-) door trigger input and (+) door trigger input and outputs for the door locks. If I connect the arm and disarm outputs to the 455t that should control the door locks correct? And not use the door lock control out of the alarm unit. I think I am confusing myself and making it harder than it really is. This is the web page of the alarm that I have.

The 445T will do all of that for you.....
Wait until you read the install manual for the 445T - everything will become clear.

I think I understand. Received the 455t in today. Found it on ebay for $10 plus $5 shipping. New unopened. Local Circuit City was $69 if I remember correct. May start in it tonight with wiring the 455t to the alarm harness. Thanks for all you help. Shouldn't have any problems but if so I am freinds with the mechanic and tow truck driver.
