now do i have to specify which firmware i need or is it universal if i do which do i get
and has anyone had any sucess with the window rollup
thanks

I just checked the service manual brake switch schematic-- the white wire at the brake switch is still (+) positive as always with GM's-  of course you should test first to verify........

Newer GM's do not need a starter wire-- they "start" themselves-- if you ever drive one- you'll soon see that you just flick the key to start position and it does the rest-- no need to hold it there until it starts- likewise- there is no "grinding" of the starter- it doesn't allow that- (meaning- if you turn to key to start with enging running- nothing happens-- go ahead and try it)-- 

The start sequence is initiated by the BCM seeing both ignition on and accessory on at the same time-- then the accesorry drops out (while ignition is still on) and this is the signal for the BCM to activate the starter-- so cut away your starter wire output from your R/S- you don't need it- and let the R/S do the rest-- pretty nice with one less wire to hook-up-

--   also as a side note: I always go with the tach sensing for Trailblazers, Envoys etc-- due to voltage sensing goes inop in really cold weather- I had three comebacks last year over this complaint- finally read all about it at the Trailblazer forums......it is real tempting to go with voltage sensing- and increasing crank time etc-- but when it is ten degrees or less out- the alternator doesn't come online soon enough for voltage sensing to work........

ok sounds good thatnks for the heads up
one more thing which bypass should i go with
i been looking at 2
xko1( dont know what firmware ver. if u could help me on that) which gives me the basics i need,bypass,locks,door trigers,etc..but do you know if the window rollup feat works

the other bypass i was looking at int-sl. has all the basic feat same but gives me the tach and the brake shutdown wire.

do you prefer any over the other or both same. like i said if window feat works with xk01 then ill go with that

is there anything else i should look for with this veh. or besides what i asked its straight foward. i think the one pain is the door triggers but the bypasses give me those so.
thanks again sorry for long post

The (+)Brake wire (it is the LARGER of 2 white wires) can be found at that OEM dual relay pack that you'll remove from the hushpad at the bottom of the dash , that harness is right next to the OBDII  connector harness (where your data wire is), and you'll be removing the OBD connector from the hushpad.  

The( -) Parking light wire is at the back of the switch, GRAY/BLK Stripe, there are two, TEST for it.   You can pop that side dash panel off to get at the light wiring, AND mount your module in there too.  It gives you easy access for programming changes. 

\

Thats it, Brake, Pk Lights, Data.   And if you want to do horn honk, BLACK / YELLOW stripe in the ignition wiring harness, get it in that junction block, it's just left of the 12V and 2 igntion wires in that junction block.  VERY easy vehicle to do.
