The Only Limit Is Your Imagination

When you think of an electrical system for your car, the first thing that comes to mind is the traditional wiring harness that you find in almost every automobile on the road. Its hundreds or thousands of yards of wires, junction boxes, relays and more. Now imagine how daunting of a task it would be to replace that harness. Wouldn’t it be great if there was an e

asier way? The ISIS™ Intelligent Multiplex System. No relays, no fuse boxes, no fixed functionality. Everything you need is contained in the system and it can do anything you want. ISIS isn’t your average every day automotive electrical system, it’s much more. It’s a complete solid-state electrical system that can be used as a stand alone system for restorations, kit car or street rod builds; OEM bus, RV or boat builds. It can be used as an overlay to your OEM system for car mods like those seen on "Pimp my Ride". Benefits include:
- Increased Reliability
- Reduced Vehicle Weight
- Reduced Installation Time
- Flexible Setup and Configuration

Your Infinitybox IPM1 Kit makes it easy to control your cooling fan. The MASTERCELL NGX takes the trigger from your thermostatic switch or ECU and tells the POWERCELL to turn the fan on and off. No external relay. No separate fuse. The POWERCELL even soft-starts the fan motor to reduce in-rush current. The MASTERCELL NGX accepts both ground-switched and 12-volt triggers natively — no extra components needed.

The Dakota Digital GRFX gauges are their most advanced dashboard system with full-color TFT displays and user-configurable layouts. Our IPM1 Kit with the MASTERCELL NGX makes wiring them even simpler. The MASTERCELL NGX has built-in low-current indicator outputs that connect directly to the GRFX controller box. Since the MASTERCELL is located behind the dash — right where the GRFX controller lives — all of these connections are short and direct. No more running wires from the front of the car back to the dash for your gauge signals. Check out the full wiring guide at the link in the comments.

We built active battery management directly into the MASTERCELL NGX.

Our inRESERVE Active Battery Management System monitors your battery voltage when the ignition is off. If the voltage drops below your configured threshold, the system automatically disconnects the battery — preserving enough charge to start the engine and protecting the battery from deep cycling.

With the IPM1 Kit, you can enable and configure inRESERVE yourself right from the MASTERCELL NGX. Pick the POWERCELL, the output, the timing and the voltage threshold. No factory programming required.

Our latest blog post walks you through the entire setup process step by step.

Your IPM1 Kit ships ready to wire, but did you know you can select your configuration right from the MASTERCELL NGX?
Every IPM1 Kit comes loaded with a base configuration that maps your MASTERCELL inputs to your POWERCELL outputs. It's the roadmap for your entire wiring project. Most customers are building front-engine cars and the kit ships with the front-engine configuration by default. If you're building a mid-engine or rear-engine car like a Factory Five Racing GTM or an Superlite Cars SL-C, you can switch to the rear-engine configuration in about 30 seconds — right from the buttons on the MASTERCELL NGX.
Our latest blog post walks you through the entire process step by step with screenshots from the MASTERCELL NGX display.

When you call or email our tech support team, one of the first things we'll ask is what software version is loaded on your MASTERCELL NGX.

Knowing this ahead of time helps us get you answers faster. The good news is that checking it takes about 5 seconds from the inSIGHT screen.

We put together a quick guide showing you exactly how to find it. Link in the comments.

Every inMOTION NGX module is now universal out of the box.
Instead of ordering a specific module for each door, you assign the door position yourself through the MASTERCELL NGX. Connect one module at a time, select the position from the menu and the MASTERCELL handles the rest over CAN.
No special tools. No programmer. Just the MASTERCELL NGX you already have in your system.

New blog post! If you're running a Holley Terminator EFI, Terminator X or Terminator X MAX, we put together a complete wiring guide showing how to connect it to our new IPM1 Kit with the MASTERCELL NGX.

The MASTERCELL NGX accepts the fuel pump trigger directly — no inVERT Mini or external relay needed. That's one less component in your build and one less thing to wire.

We also cover the cooling fan connections, ignition power, and the differences between all three Terminator systems in one post.

Running a Holley Sniper EFI? One of the most common questions we get is how to wire it with our Infinitybox system.

Our new IPM1 Kit with the MASTERCELL NGX makes it simpler than ever. We cover everything — key-on ignition power, the fuel pump trigger, and the cooling fan trigger. Fewer components, less wiring, and a cleaner installation.

Our latest blog post walks you through every connection with a full wiring diagram.
