1999 jeep grand cherokee interface module

I am looking for a Immobilizer Override and Databus Interface module for a 1999 jeep grand cherokee. I don't own any programmers. Can someone direct me to one which has the firmware pre-loaded from the manufacture. Thank you.

The best choice is the iDatalink ADS AL CA flashed with the ADS-AL(DL)-CH6 firmware.

I have used this module with excellent results.  The door locks and Factory Alarm are a PITA and this bypass module handles that well.  While it is a registered dealer only flash, there are several online stores that will flash the module for you prior to shipment.  Here is a link to the install guide : http://cdncontent2.idatalink.com/corporate/Content/Manuals/DL-CH6/ADS-AL(DL)-CH6_20110829.pdf

The other option is the Fortin INT-SL+ bypass module.  It comes pre-loaded and all

ready to go right out of the box.  I have not used this module on a Jeep but have onother vehicles with excellent results.  Here is a link to the install guide :  https://ifar.ca/download/3966/preview.html

There are modules from XPressKit ( Directed ) but most require a flash procedure prior

to install.  Same goes for the newer Fortin EVO-ALL's because they dropped support for J1850data after Firmware Rev 4.06.

Soldering is fun!
