Be gentle – the high voltage wire is tiny to get the number of windings in there for the needed high voltage. The wires are soldered to a "L" shaped tab that is taped to the coil. Excessive heat can damage the tape. Pulling or twisting can damage the connection. I clip the old wire (If soldered) leaving solder on the coil. Pre bend the new wire so the tinned end rests against the coil solder. Then touch the iron to the wire just long enough for the solder to melt around it. Good connection – no strain on the tab. . . 😉
