Thank you for visiting the Infinitybox website. This list includes some of the most common questions that people ask about wiring their cars & trucks with our system. If you don’t see what you need here or if you need immediate assistance visit our contact page.

Will it work for my vehicle?

The most common question that we get is “Will Infinity Box work for my vehicle?” If your vehicle has a 12 or 24-volt DC system and you need to turn things on and off, Infinity Box is the system for you. It doesn’t matter if you’re building an armored vehicle, a bus, a dragster, a tactical truck or a hot-rod, Infinity Box is the most flexible, versatile and functional vehicle power management system in the market.

How do I wire in a Gen-II Mini from Vintage Air?

For the Gen-II, there are two wires you need to worry about. One is the red wire. This is the primary power and it should be connected directly to the battery or some other constant battery feed. The second it the purple wire. This is your ignition power feed and it energizes a relay to power on the system. You should splice this purple wire into your POWERCELL ignition output.

How do I remove unused wires from the MASTERCELL or POWERCELL connectors.

You can easily remove any of the unused wires from the MASTERCELL and POWERCELL connectors.

For the POWERCELL connectors, first remove the blue TPA (terminal position assurance) clip from the back of the connector. Then, simply insert a small blade into the slot on the front of the connector. This bends down a locking tab on the terminal. Once you do this, you can pull the wire out of the back of the connector. Replace the TPA when you are finished.

For the MASTERCELL, unclip the retainers on the front of the connector. There are two small white tabs on the sides that hold them on. Each terminal is held in with a small white plastic finger on the connector. You can gently lift these white fingers and pull the unused wires from the back of the connectors.

What Happened to ISIS Power?

Nothing happened to us as a company. We made the decision to drop the ISIS Power brand due to events happening in the media related to the Islamic State. We have been Infinitybox since our inception in 2008. The team is the same, the products are the same and we continue to develop new products to make wiring vehicles easier.

What do I do for reverse lights in my car?

Not every car has reverse lights so we don’t define one specifically. You can use any of the open outputs on the rear POWERCELL for these. Simply connect the corresponding MASTERCELL input wire to the reverse switch on your transmission.

My company builds commercial vehicles. Will the Infinitywire system work for our applications?

The Infinitywire system was originally designed for commercial vehicles. It was tested and qualified for some of the most extreme applications including construction, agriculture and military trucks. Our hardware is presently used in service trucks, first-responder vehicles, armored trucks, busses, coaches, RV’s and military tactical vehicles. Contact our sales team to discuss your specific application.

Can I power multiple things from a single POWERCELL output?

Each POWERCELL output can supply up to 25-amps. The answer is yes. For example, you are going to use your ignition output to power your ignition system, your gauge power, your audio power and your heating & A/C.

Do I need to add relays to my electrical system?

Typically no. The POWERCELL has solid-state relays built into it with fuses to protect the output wires. Each output can supply up to 25-amps, which will work for the majority of applications in your car or truck.

The only time you would need to use a relay is when you are powering something that draws more than 25-amps continuously.

What size fuse shoudl I use for the POWERCELL outputs?

Remember that the fuse is designed to protect the wire not the thing at the end of the wire. All of the output wires in the Infinitywire are 14-AWG. This blog post has more information and some guidelines.

What is the difference between the 10-Circuit and the 20-Circuit Kits? Which one do I need for my car?

A lot of people ask: “Do I need a 10 or a 20-Circuit Harness Kit for my car?” The answer is, it depends. Both the 10 and 20-Circuit Harness Kits use our rock-solid multiplexing technology. The only difference between the kits is the number of POWERCELLs that you get. The 10-Circuit Kit gets you one MASTERCELL and one POWERCELL. The 20-Circuit Kit gets you one MASTERCELL and two POWERCELLs. Each POWERCELL has 10 outputs. When you sit down and look at the number of things that you have to control in a basic car, you can handle most all of them with the 10 outputs on a 10-Circuit Kit. This includes things like the starter solenoid, ECU power, headlights, turn signals, parking lights, etc. Wiring your car with a 10-Circuit Kit can be a lower cost option to get more advanced features in your car. You have the option to add practically any of our Infinitywire accessories to the 10-Circuit Kit including inLINK for security functions, inTOUCH NET for touch screen control and inMOTION to control windows and power locks. Going up to the 20-Circuit Harness Kit gets you some significant advantages over the 10-Circuit Kit.

  1. The extra POWERCELL gets you 10 more outputs. This gives you more flexibility to control more things through the Infinitywire system.
  2. Having two POWERCELLs lets you put them where you need them in the car. With two POWERCELLs, you can place one in the front of the car and one in the rear. This means that you’re running less wire because you can wire things to the local POWERCELL. Examples here include the turn signals, which are on the front & rear of the car. The parking lights are another example since they are in the front and rear of the car. With the single POWERCELL in the 2-Cell Kit, you have to run all of the wire back to a central location. With multiple POWERCELLs you have more flexibility and can run less wire.
  3. The extra POWERCELL in the 20-Circuit Kit gets you more flexibility to control your tail lights and turn signals. A lot of late 1960’s cars use a single filament of one bulb on each side of the car for both the brake lights and the turn signals. We call this a single-filament configuration. The filament on each side of the car flashes independently as a turn signal or both sides turn on together when you step on the brake lights. The 20-Circuit Kit is set up to manage this turn-signal and brake light function within Infinitywire. You can’t do this directly with the 10-Circuit Kit because you only have one set of outputs for the turn-signals spliced to the front and rear of the car. If you did this with the 10-Circuit Kit, your front turn signals would turn on when you stepped on the brake pedal. There is a fix for the 10-Circuit Kit in a car that needs a single-filament configuration that involves a trailer converter. Give our tech guys a call if you want to go this way.

We have a configuration sheet specific for the 10-Circuit Kit. Click on this link to see it. This link will take you to an example of one of our 20-Circuit Harness Kit configurations. This one is for our front-engine set up. At the end of the day, you can wire a basic car easily with our 10-Circuit Kit. You get all of the benefits and add-on capability of the entire Infinitywire system. However, adding the extra POWERCELL expands the flexibility of the system significantly.

Which head units will work with inTOUCH NET?

inTOUCH NET can be controlled by any touch screen device that has Wi-Fi and a browser.  This includes the iPad, iPhone, Galaxy tablets, Windows Surface and many other devices. 

For head units, the most common is Kenwood’s DNN992.  This one is Android-based and has a built-in browser and Wi-Fi.  Here’s a link to it. 


The other one that some customers have used is manufactured by Parrot.
