Yes I did every thing that was told to do

 

Just swapped my overhead console. Took a console from a short (sunroof model) 99 Trailblazer and put the computer in my 02' (long console) and it fit perfectly. Factory wiring in the 2002 was not the same however, so I took the whole harness from the 99 (located behind the dash on the driver side) and ran it all the way up the pillar and installed. Harness will power both visor mirrors, and had to splice a 5 pin connector into a 4 pin to make the courteousy lights work.

Other than that, she fits and operates perfectly.
