HI-6S IGNITIONFor more information, see www.cranecams.com

CAUTION: READ INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION.

OVERVIEW—READ FIRST!Before proceeding with the HI-6S installation, read the introductory material below and on pages 2–4. Then use the Applications Index to find the appropriate section for your vehicle.

INTRODUCTION CraneHI-6Spartnumber6000-6300isforgeneralpurposeapplications.Partnumber6000-6301isforFordTFI-IVappli-cations.Partnumber6000-6302isforlatemodelGMapplica-tionswithdualplugcoil.

The Crane HI-6S is a multi-spark inductive ignition spe-cially optimized for street drivenperformancevehicleswithanengineredlinebelow8,000RPM.ARISCmicrocontrollermanagesall functionsof theHI-6S including thestage revlimiterandtimingretardfunctions.Ifrevlimiterortimingretardfunctionsarenot required, theHI-6Salsohasananti-theftfunctionthatusesaswitchhiddenunderthedashtoselectaverylowrevlimittokeeptheenginefromstarting.

WhiletheHI-6Shasarangeofbuilt-inretardfunctionsinclud-ingboostproportionalretardusinganoptionalboostsensor(P/N 9000-0110), use of these built-in retard features pre-cludesuseofthebuilt-inrevlimiter.Ifanapplicationrequiresbothrevlimitingandretard,youwillrequiretheoptionalTRC-2TimingRetardControl(P/N6000-6425).Refertopage14.

TheHI-6S is intended for usewith vehicles equippedwithoriginal equipment (OE) electronic ignition and computer

CAUTION: WHEN USING THE RELAY CIRCUIT SHOWN,YOU MUST ALSO ADD A DIODE BETWEEN THEVOLTAGE REGULATOR AND CHARGING INDICATORLAMP AS SHOWN IN FIGURE 10 TO PREVENT RUN ON.

USE HEAVY GAUGE16 AWG STRANDED WIRE

FOR OPTIMUM RESULTS-REPLACE WITH CRANE LX91 COILNOTES:

1. Use relay as shown to supply direct +12V power to HI-6S and coil.2. Refer to Figure 2 for cylinder select and additional signal hookup.3. Use 1/4" female quick disconnects for relay connections.
