One of the bcm codes that I am getting shows a faulty theft deterrent module. Does anyone know where this is for a 99 denali? Apparently its in a different place than Yukon/Tahoe??? I tried searching but didn't find anything. Thanks for any help

Mine isn’t where the video says it is, mines a 02 TahoeIn my 99 suburban, it was under the dash behind the panel under the steering wheel. You have to dig for it as it is attached to the metal framework. It is wedged up there pretty good and a real pain to get to.
I found some you tube videos on it. I'll go see if I can find it again and link it here.
