Okay this one is easy. Okay follow the hose from your airfilter to your intake manifold. Before air can get into your intake manifold you´ll have the throttlebody. The throttlebody on the engine side has a wire that goes into a circle. This is your throttle cable. If you rotate the throttle you can feel the plate in the throttlebody open and close. Okay, now directly on the opposite side of the throttle cable assembly is the TPS. Its about 3.5" wide, about 2" high, and about .5" deep. It should be completely black. It will have a little dovetail wiring harness on it.
