I am doing a LS2 swap with an 06 Trailblazer ECM.
I have a harness and need to know exactly where to hook up the TCC wire coming from C1. The harness I have simply says "brake switch" problem being there are 4 wires that need to be connected to the brake switch. I am getting conflicting info from the harness manufacturer. Their instructions show the NO/NC brake switch. When I called to verify that the TCC wire went to the NC side (hot when brakes not applied, nothing when applied). I was told that, "all the ECM wires should be connected to the same wire the brake lights are connected to"
Does anyone have any better information on the 06 trailblazer TCC connection.
As far as I am aware this is an 06 TB only computer?

Does page 12 of this doc help?

Someone told you wrong.
The TCC wire needs to go to the NC side. (hot when brakes not applied, nothing when applied)

These Instructions are much nicer than the ones I got with my harness......
