Holley Sniper EFI HyperSpark Distributor Kits
Holley Sniper EFI HyperSpark distributor kits were designed to make upgrading your ignition on a Sniper EFI-equipped engine simple. When installed concurrently with a new Sniper EFI system, the combination creates the easiest way to install EFI conversion on the market—and only four flying lead connections are required! The harness only requires one connection to a switched power source, battery positive, battery negative, and fuel pump power. The pre-terminated connectors and a built in 40A relay provides power to all of the components within the system. With the included Sniper EFI main harness you no longer need to run multiple wires to provide switched power for each individual component, which not only helps prevent wiring confusion, but it will also speed up your install time and clean up your engine bay. Simply route the harness and pre-terminated connectors to your HyperSpark coil, distributor, and ignition box and plug them in. Available for all popular engine combinations, these kits come with a distributor, coil, ignition box, and an integrated Sniper EFI harness. Order the application you need. Key features: * Plug-and-Play Sniper EFI main harness replaces the standard Sniper EFI harness with four loose leads, battery positive, battery ground, switched 12 V, and fuel pump power, for a simple and streamline installation * Designed for existing or new Sniper EFI installations (the HyperSpark Master Kit harness retains the same flying lead wire colors as the Sniper EFI main harness; new installations will not use the Sniper EFI standard harness or coil driver * Complete ignition system in a box, including: HyperSpark ignition box, HyperSpark ignition coil, HyperSpark distributor (for your application), and a plug-and-play main harness * HyperSpark distributors feature a Hall Effect crank trigger sensor providing a noise-free rpm signal to the Sniper ECU * Patented clear installation cap eliminates any confusion while installing the distributor * HyperSpark CD ignition box is seal and powder coated to be installed in the harshest of locations * External LED on HyperSpark CD Ignition box helps verify 12 V, cranking rpm, and low battery voltage * 135mJ of spark energy when used with the HyperSpark ignition coil, ensures complete combustion * Integrated ignition coil bracket simplifies mounting the Ignition coil * Ignition coil connector removes any doubt of loose connections at the Ignition coil * Enables timing control on a Sniper EFI Installation

MSD 6-MOD Ford Modular Engine Controller
The 6-Mod Ignition Controller was originally developed for the 4.6 and 5.4-liter modular motors that were fed through a carburetor rather than an electronic fuel injection system. However, with the useful options that the 6-Mod provides, such as two rev limits, a step retard and easy control over the timing, the EFI people wanted a way to take advantage of the adjustment. The harness kit provides a splice-free installation of the MSD 6-Mod Controller to factory equipped EFI vehicles making installation a snap. All of the connectors plug directly to the factory units so there is no cutting or splicing of your factory wires. Once installed, the 6-Mod allows users to advance or retard the factory's timing curve, program a step retard for use with nitrous systems or even map out a timing curve through a laptop by using MSD's Pro-Data+ software.
