Using MSD’s DIS-4 ignition systems on your coil-on-plug Ford has always been a great upgrade, but honestly, the wiring poses quite a challenge. To ease this install, we now offer a wiring harness kit that’ll make the install nearly a direct plug-in!The harness provides a splice-free installation with connectors that plug directly into the factory unit. They even have corresponding wire colors! When used in conjunction with two DIS-4 Ignitions and four Dual Ignition Adapters, PN 89121, your coil-on-plug Ford will receive all the spark it needs plus a two-step rev limit and step retard. And the best part, wiring will only take about an hour!
The DIS Ignitions all deliver a stout, CD spark that is capable of burning the majority of air/fuel mixtures. There are of course exceptions, such as full bred race engines running high boost pressures from turbos, blowers or nitrous. To answer these needs, we offer a Higher Output version of the DIS Ignition Controls.The DIS Plus HO Ignitions produce an incredible 170 millijoules of spark energy with 470 primary volts. This increased output will light up fuel mixtures even under extreme cylinder pressures.The DIS-HO boxes are not CARB approved and are designed for drag racing applications only.
