10-Circuit vs. 20-Circuit Kits

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 Infinitybox 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 Infinitybox 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 Infinitybox.  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.

The other thing to consider is that the 10-Circuit Kit may not get you all of the outputs that you need to make your car street legal.  Talk to our team to verify.

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 Infinitybox system.  However, adding the extra POWERCELL expands the flexibility of the system significantly.
