We have our Infinitybox systems powering cars all across the world.  One of our Australian customers just sent us some great pictures of his Cobra replica.  Peter K. started building this car in February 2012 and finished it in November 2017.  The car is wired with our Infinitybox system and has been running flawlessly on the road.

Peter wired the car with our Infinitybox 20-Circuit Core Kit.  Our engineering team customized his system to accommodate some of his unique requirements for the Australian market.  He also added inLINK for security, immobilizer and other remote features.

Peter mounted the MASTERCELL and the front POWERCELL in the footwell on the left-side of the car.  Since this is a right-hand drive car, this is the passenger side.  His front POWERCELL is powering the ECU, the starter solenoid, the headlights, high-beams, front turn-signals, front parking lights, cooling fan, horn and dash.

This picture shows the locations of the MASTERCELL and front POWERCELL.

He made a clever interior trim piece that hides both the MASTERCELL and front POWERCELL.  At the same time, it gives him easy access to these cells for troubleshooting and diagnostics.  Here is the trim piece in stalled with the panel open to the MASTERCELL.

Here is the trim piece with the MASTERCELL panel in place.  You can see how easily the electrical system in this car disappears.

His rear POWERCELL is mounted in a compartment in the trunk.  This rear POWERCELL is controlling the brake lights, rear turn-signals, rear running lights, fuel pump and other accessories in the rear of the car.  This picture shows the POWERCELL mounted in the rear of the car with the battery and the primary fusing.

Peter installed the Ford Racing Coyote engine in this Cobra replica.  You can see how neatly this engine fits under the hood of this car.

Illegal Garage’s Alumacobra Switch Install

We just received a great video from a local customer building a Factory Five Roadster.  Jose G. has been building this car for a few years and he’s wiring it with our Infinitybox system.  He is installing our 20-Circuit Kit with inLINKThis link will take you to an earlier blog post covering his progress.

He has a very slick and elegant aluminum dash that has modular panels.  He can easily remove and install panels for his switches and gauges.  It would certainly make working on the dash very easy.  Jose was recently at the London Cobra show in Ohio and saw a new set of switches he wanted to integrate into his dash.  These are nice looking billet buttons and he wants to use them for his lights, fans, wipers, fuel pump and one-button start.  These buttons are from Billet Automotive Buttons in Australia.  Installing these buttons shows the simplicity and the ease of wiring your car with our Infinitybox system.

First, our MASTERCELL inputs are ground triggered.  This gives you a lot of flexibility of how you can wire your switches.  This simple diagram shows how you wire a MASTERCELL input to your switch.

You can click on this link to get a more detailed blog post talking about wiring switches.

Another significant advantage of wiring your switches with our Infinitybox system is the fact that it takes very little current to turn on an input.  It takes less than 1 milliamp (1/1000 of an amp) to trigger an input.  That gives you the flexibility of using any switch to control the functions in your car.  With a lot of billet buttons, you have to use them to trigger a relay because they cannot handle the full load current of things like lights, starter solenoids and fans.  This is very easy with our Infinitybox system.

Since it takes so little current to turn on a MASTERCELL input, you can use very light-gauge wires between your switches and the MASTERCELL.  Our standard harnesses use 22-AWG wire.  This helps keep behind your dash clean and easy to service.

Lastly, we give you the power of advanced electrical control functions.  In the case of Jose’s car, he’s using our One-Button Start feature.  A single MASTERCELL input connected to a momentary button lets him start his car with ease.  Check out this blog post for more details on our One-Button-Start feature.

Jose just posted a great video to his YouTube channel, The Illegal Garage, showing off how he installed these billed buttons into his Cobra.  You can check it out below.
