Ignition Module I used in the video GHP 39E0-0008-00( any 39E0-00**-** will work the same the length of the leads is the only difference)
If you're replacing a single wire ignitor with one of these 2 spark plug lead wires units; ONE lead will hook to the existing spark plug and the other lead will ground out to the frame or housing that makes electrical contact with the outside(threads) of the spark plug. You can flatten out the end and put a screw in it or something similar.
