John,

there is no resistor. the wire itself is the resistance. Its a special type of wire designed for that purpose. From ignition switch to coil, the wire provides the needed resistance of approximately 1.5 ohms. The relay coil is approximately 73 ohms, so the voltage drop across the resistance wire is 0.27 volts, and across the coil of the relay the voltage drop is 13.38 volts (assuming a 13.65 volt system) which is sufficient to activate the relay coil.

Just hook the light blue wire to terminal 86 of the relay, terminal 85 to ground. If your new ignition requires a resistance, you'll hook a new resistor between terminal 87 and the new ignition.
