Hey thanks jrdiesel Ill check it out and see if I can find them I took the instrument cluster off to to run my gps antenna through it and didnt even bother too look. but when you say behind the instrument cluster its not the harness the cluster is attached too? because i remember when i took it out there was a metal plate with bolts on it is it behind that? also for the fuse panel there is a few harnesses there too do you know which one? Thanks.

Hello I have not attached this wire because I cannot find it? Does anyone know its location on a 05 Trailblazer no Onstar or Bose? I found it in my Haynes book as the Purple white wire and light green/black? Also if you know where it is which one do I splice into? one says VSS LO and the other VSS HI?? The Avic Book says its in the glove box but I took it off and theres a harness there but no purple or lt grn wires anywhere? Also if you have done this on a TB and know where is the reverse wire location I would appreciate it too I will be installing one soon. Thanks!!!

I bought it off Ebay hchavez? do I still have warranty with Scosche? mod187 I dont have onstar and I got the harness that was for trucks without onstar? Im thinking of buying another one and switching out the computer only then if it still fails at least i know its not the computer. Another thing i just noticed when i drove it an hour ago it worked but there was a light on my dash saying the 4 wheel drive needs servicing wtf??? I didnt touch anything that woudl affect the 4 whl drv I checked to make sure the connection was good because I did remove it to install this thing the kno

Thanks for the reply Mod187. I drove it this morning and it did not turn on went to my moms then to work nothing went on an errand then just like that it turned back on? now its on but Im sure when I go to lunch it will turn off again? Im going to buy a new harness and replace the computer part of it I went throught his thing meticulously when wiring it together and put the red with red and yellow with yellow then grounded out the red/yellow the parking break and the radio itself. It seems weird to me that it will work sometimes then other times its like it has no power at all??? no chime

Hello all. I just installed the F90BT in my 2005 Trailblazer. At first when I turned on car I got nothing so I figured I did something but I bought the correct harness for my car the one that sends the ok status to my cars computer and gives a switched 12V to the radio. after a few minutes and a few key turns turning it on and off it finally turned on so i thought i fixed it then it turns off again and restarts over and over, ok so i figure its the unit get it exchanged get a brand new one pop it in and it turns on fine works perfectly test it for 15 minutes straight no problem. Then I tu
