How to Install Nology HotWires to a Nology ProFire

Nology is a company that manufactures ignition components for cars and motorcycles. HotWires are spark-plug wires that carry high-voltage electric currents to the spark plugs that fit into gasoline-engine cylinder heads; a mixture of gasoline and air explodes in the cylinder when the current jumps between the two electrodes on one end of the plug. The spark-plug wire fits onto the opposite end of the plug; the other end of the spark-plug wire connects to a current-generating device called a coil. The ProFire is a Nology-brand coil that the company recommends for use with its spark-plug wires.

Instructions

1

Measure and cut the HotWires to a length that is 1-1/4 inches longer than your original spark-plug wires; Nology Hotwires are longer than stock and must be cut to fit. Measure the wires with a steel measuring tape and cut them with side-cut pliers.

2

Slide a spark-plug wire spark-plug boot onto one end of each cut wire.

3

Strip 5/8 inch from one end of each wire using the 14-gauge notch on a wire stripper crimping tool.

4

Fold the exposed core of the wire back against the intact wire (working one wire at a time). Slide a spark-plug wire terminal over this portion of the spark plug wire to secure the wire core in place.

5

Crimp the spark-plug terminal on all sides using the 7/8 mm notch on a wire stripper crimping tool.

6

Slide the spark-plug wire boot over the spark-plug terminal of each spark-plug wire.

7

Attach a spark-plug wire terminal and a spark-plug wire coil boot to the opposite end of each spark-plug wire following the same procedures you used to install a terminal and boot to the spark-plug end of each wire.

8

Plug the spark-plug boot onto a spark plug and plug the coil boot onto the appropriate connector on the coil (working one wire at a time). On a V-Twin motorcycle, for example, the coil connectors are marked front and back for the front and back cylinders on the bike. With other motorcycles and automobiles, the coil connectors will be numbered according to the number of the cylinder so that, for example, the spark plug in cylinder four should connect to the coil connector marked 4.
