Noise in 340...help

Drag 340 might have something. The wire that I found that I knocked off "seemed" to go from the electronic ignition module to the ballast resistor. I looked online before I attached it there and from my reading it appeared obvious that's where it went....since immediately upon attaching there the car started. Drag340 is suggesting that I may have attached it at the wrong terminal causing an ignition problem/noise. As a matter of fact the noise the car made upon start-up reminded me of another 340 I had that had a timing issue at one time. But that car didn't knock AFTER start-up. The wire in question is light blue with a yellow stripe. I attached it to the left terminal on the ballast resistor. The other terminal had two wires connected to it running from the voltage regulator. Again.....your suggestions are welcomed.
