Car Alarms: replacing or up grading, trailblazer ext, plug n play

Question
I HAVE AN EXCALIBUR AL-2000-E IN MY 2003 TRAILBLAZER EXT. DO THE MAKE A BLADE TECH BRAIN THAT I CAN JUST PULL THE OTHER BRAIN AND REPLACE WITHOUT HAVING TO REWIRE THE HOLD TRUCK AGAIN. I WOULD LIKE TO HAVE THE UP DATED TECH WITHOUT HAVING TO BUY A WHOLE NEW SYSTEM AND REWIRING THE TRUCK.

Answer
No sorry, you'd have to rewire the plug in harnesses
to accomodate Blade tech. This would not be
able to be retro fit to the older harnesses
by plug in. They could be tapped faily easy since
they do the same things Blade needs, but
still not a plug n play deal.

Again, sorry, it won't apply here.
