Hey guys, I'm sure this has been brought up but I couldn't find the details that I need. I have a 68 Firebird with a 5.3 LM7/LS1 with a 4L60E transmission. The guys that built the car didn't hook up the brake switch to the TCC/brake switch input on the ECM. I see the output to the Trans is connected. How does this get wired? Am I sending 12vdc to the normally open switch which then sends the 12vdc to the ECM when I press the brake or is it the other way around? Do I use a normally closed switch to constantly send 12vdc to the ECM until I press on the brake to cut the 12vdc to the ECM? Any help would be greatly appreciated. Thanks
