The IAC is attached to the main wiring harness.
The ignition amplifier is attached to the main harness with the connector at left side of lower diagram. The ignition amplifier should
be mounted on the firewall, or on the passenger fender well. The KEY ON (Start/Run power) wire (pink) should be connected to the
factory positive (+) coil wire. If you have a ballast resistor in your factory coil wiring, you should remove the ballast resistor and
connect the KEY ON wire to the wire coming into the positive (+) side of the ballast resistor.
REFER TO VEHICLE REPAIR MANUAL
FOR WIRING DIAGRAM, IF NECESSARY.
The coil is attached to the main harness. We strongly recommend using an E-Core type (non-ballast resistor) coil as shown below.
These are available through most performance ignition parts suppliers. The coil attaches via the connector shown below. If using a
standard style coil, cut the connector off and use ring type connectors.
