JEGS 555-40805 Ignition Control Unit Notes:
- Case must be grounded. Be sure mounting location (firewall, bracket, or fender apron) is free of rust & paint (sand or wire brush as required) before mounting Ignition Control Unit. Make sure the mounting screws are tight and use Serrated-head screws or external-tooth lock washers to mount the Ignition Control Unit.
- Coat connector pins with silicone grease. Be sure wiring connector retaining screw is present and snug.
- Plugs into all Mopar OEM, JEGS, and Mopar Performance wiring harnesses, whether the harness or vehicle was designed for 4 or 5-pin Ignition Control Units. No modifications required.
- Use with ballast resister. Works with 2-Pin or 4-Pin ballast resistors. Use without ballast resistor will destroy the Ignition Control Unit.
- Use with OEM or OEM-Spec (oil filled) ignition coil. E-Frame coils are also acceptable. High Performance Coil 555-40105 is also recommended. Coils made for C-D ignitions (MSD, etc) may destroy the Ignition Control Unit. Coil Primary resistance should be no lower than 1.4O
- Pre-startup test (recommended for vehicles that has experienced Ignition Control Failure). Connect a voltmeter between the coil positive (+) and a good ground. Turn ignition key to "run" position. Voltmeter should read between 7.0 and 9.0 volts. If higher turn ignition key off immediately and check ballast resister (resistance - too low 0.5O minimum, 1.0O recommended for most street applications), ballast wiring, shorted coil, ignition switch wiring, etc.
- Quick Wiring Check - Disconnect either ballast connector at idle. Engine should stall instantly.
Emissions Note:
This part is only legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles or on vehicles used solely for the purposes of closed competition racing.
