I just wanted to know how hard it is to actually get rid of the TCS systed. when I pulled out the harness the only thing it was connected to was a heat sensor on the engine and the transmission. all of the other plugs were no plugged into anything. Will this affect my trucks Engine? or can I just throw it all was and plug the hole in the firewall???

That was an early attempt at polution control. All it did was keep the vacuum advance from working until the trans was in high gear. Just dissconnect it and hook the vacuum hose from the disribitor to the carb like normal.
