serial 2 data line, help(pic) this is on a 05 trailblazer 5.3, im haveing trouble with my scanner being able to communicate with the ECM, i have the C1 15 ylw wire going to the pin 2 on the DLC port... does the theft deterent or BAE need to be hooked up? if so any way i can program that out of the computer so it wont need to be hoooked up?
i do not have the high speed GMLAN serial data wires with the 121ohm resister hooked up yet, do i need to, to communicate with the ECM?

You have to hook up the LAN data lines. That's where the engine data is.
