You DO need a ByPASS..........

I use the OMEGA IM-01 , if you want to do ByPass & Door Locks or IB-PLJX

You need a bypass, i.e. Bulldog 791 will work good because it's self-learning - no ohm readings required and no dip switches to set. If your designtech unit also has keyless entry and you are planning to hook it up to the trailblazer without a gm databus interface module, good luck - it could easily take you 2 or 3 days to hook up with the module. If you are installing keyless, I suggest DEI 457G. They work GREAT and will save you LOTS of time and frustration.The Badger
