idatalink bypass in an 01 grand cherokee

Thanks for the update. 

You are absolutely correct.  You had the older style transponder loop with your CH1 module that were very common a few years ago.  Sometimes the older modules will have a white sticker on them that ID's the H/W version, Firmware version and the install guide number.  All the newer modules have that white sticker. 

Glad it's working OK now.
