I am screwing with this harness trying to wrap up my lt1 4l60e conversion. THe schematic shows a tcc/brake interupt and a PNP (park nuetral postion) switch. THe tcc interupt is supposed to go to a brake switch i think, then the pnp to the shifter. Both these systems plug into the pcm. any pointers on the wiring would be awesome!

UMMm whats a tcc? sounds like what you have is a neutral safety circuit and a cruise control cutout circuit. The neutral safety circuit would go to the shifter to prevent starting in anything but park or neutral. This would be different with a manual trans as the circuit would run through a clutch switch which would only allow start if the clutch were depressed. The cruise control cut out would route through the brake pedal switch and disconnect the cruise control when you step on the brake.
The TCC is Torque Converter Clutch, and yup the brake switch is the place you need to go to get an interupt for the signal. As for the PNP, they are really called PRNDL switches. There are two different types depending on what system or car/truck it came from. If you get that I can get you the diagrams and the part is fairly cheap.
