my friend has a 00 civic si with a venom intake manifold. there's one sensor thats not plugged into the manifold and he can't figure out where to put it. its the black tube-looking sensor that goes on the back of the stock manifold, and has a gray plug connected to it with 2 wires. does anybody know where to put it on the venom manifold? better yet, does anybody have pics of the back of their installed manifold with all the sensors on and stuff?
