Replacing the knock sensor and found the wire to be completed cut. I assume the one i have pictured is the correct one because it was in the same general area and its cut. only minor problem is that i found a missing ground wire that WAS located on the intake manifold. picture is of broken wire i found along with 2 other wires in same area and knock sensor plug/wire. Will also be re wiring the plug with 16gauge wire due to brittle shape of wire if anyone has advice. thanks for any help in advance!
