INSTALLATION INSTRUCTIONS for HI-6 CD IGNITION WITH REV LIMITER AND TIMING RETARD Part Numbers 6000-6400, 6000-6420, 6000-6421, 6000-6422, 6000-6423, 6000-6424, 6000-6425, 6000-6466 CAUTION: READ INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION. READ THIS BEFORE YOU BEGIN! Before proceeding with the HI-6 installation, read the introductory material below so that you will understand the basic features and operation of the unit. The installation instructions are organized by application; use the Applications Index to find the appropriate section for your vehicle. For HI-6 Part Number 6000-6466 or hookup of optional TRC-2 Timing Retard Control Part Number 6000- 6425, additional information is provided in the TRC-2 supplement starting on page 21. CAUTION: READ THE FOLLOWING CAREFULLY: • Standard HI-6 units (6000-6420, 6000-6421, 6000-6422, and 6000-6423) are sealed for protection against occasional water drips. However, standard HI-6 units MUST NOT be mounted in areas exposed to water splash or sprayed with water. Moisture forced into the HI-6 unit can cause an internal electrical short circuit. This could destroy the HI-6 unit and VOID YOUR WARRANTY! • If you are mounting a standard HI-6 unit in the engine compartment, direct the cable exit down, so that moisture can drain out. Always cover the HI-6 unit when cleaning the engine compartment. • Severe automotive environments and race applications require the HI-6R (6000-6400), HI-6DSR (6000-6424), or part number 6000-6466 (HI-6R and TRC-2 kit) . Marine applications require the HI-6M (6000-6462) . These HI-6 versions are fully encapsulated with urethane and include wire harnesses with Weather Pack connectors. • Make sure that all original equipment wires are disconnected from coil. GM coil-in-cap HEI: Install black ground wire as shown in Figure 5 or 7. • Tape up any unused wires after completing the installation. If the magnetic trigger leads are not used, cut short and tape up each lead APPLICATIONS INDEX Late Model Computer Controlled Vehicles with Stock Electronic Ignition . .

INTRODUCTION The Crane Cams HI-6 is an advanced capacitive discharge (CD) type ignition system intended for racing and performance street vehicles. The HI-6 is 50 states street legal (California Air Resources Board E.O. D-225-52 and D-225-63 for 1995 and prior non-OBD II vehicles) and can be installed inmost vehicles. Trigger sources include: • Electronic ignition module • Magnetic pickup distributor • Crank trigger system • Points distributor CAUTION: The HI-6 is not compatible with any odd firing engines or distributorless ignition systems. Use the HI-6DI2 (part number 6000-6500) for distributorless ignitions. 530 Fentress Boulevard, Daytona Beach, FL 32114 Tech Line: (386) 258-6174 Fax: (386) 258-6167 Check our web site for [updates: www.cranecams.com](updates: www.cranecams.com) 3/99 1 9000-6000C Figure 1.

FAQs

Which application section should you use for a specific vehicle when installing the HI-6?

Use the Applications Index to find the appropriate section for the vehicle, since the installation instructions are organized by application.

What are the key compatibility restrictions for the HI-6 ignition system?

The HI-6 is not compatible with odd firing engines or distributorless ignition systems. Use the HI-6DI2 (part number 6000-6500) for distributorless ignitions.

How does the digital sequential stage rev limiter work on HI-6 units?

The stage rev limiter can be set from 600 to 9,900 RPM in 100 RPM increments using rotary switches. Applying +12V to the yellow/white wire activates the stage limit; otherwise the maximum rev limit is selected. Firing is sequentially controlled at the rev limit to keep RPM within a narrow band.
