Knock Sensor Wiring

The wire coming off of the knock sensor is DARK BLUE, but mine has gotten severed and I am unable to find its other end. The only other wire close to it that isnt connected to anything is a PURPLE wire that has a single connector similar to the connection of the O2 sensor. Does the DARK BLUE wire connect to the PURPLE wire?

The knock sensor wire goes to the ESC module (5 wire connector),this is bolted next to the trottle body on top of the intake manifold.

Connector at the ESC module(electronic spark controll module) are :

A: not use

B: ignition voltage-pink/black

C: ECM signal------black,yellow/black or yellow/red

D: ground----------brown or black/red

E: knock sensor---dark blue
