It is imperative that the module case be grounded securely to the body, the module is grounded through the case. Failure to secure a good ground on this unit will cause failure of the Micro Processor and void your warranty. Clean the chassis mounting points to bare metal to ensure a perfect ground. If in doubt add a 12g wire to the mounting screw and run it to a clean ground. The engine must be grounded through a correct and large enough strap to the chassis to insure correct grounding. You must eliminate the ballast resistor either by soldering the wires together or using our jumper wire kit. If the LED does not come on steady within .5 seconds of ignition switching on -Check Ground.

Do not attempt to run this ignition system with an aluminum contact distributor cap, cap and or rotor failure will occur.
4 Pin Vs. 5 Pin…. all replacement modules for Chrysler Ignition systems use a 4 Pin connector. The older style 5 pin connector just plugs into the 4 Pin Module. Except Dodge Trucks with the Heavy Duty Emissions Cycle Carburetor with Electronically Controlled Vacuum Kicker. Which is not the correct application for the FBO Ignition system.
