Install in an MGA
We love to see our customers’ finished wiring jobs with our Infinitybox system. We just got a set of pictures showing off an Infinitybox install in an MGA. Leverett F. did an awesome job of restoring this car from 1957. The overall job included a full rewire of the car. As most folks know, British cars of this vintage are plagued with gremlins baked into the Lucas Electronics components. Leverett wanted them all gone and wanted to start over with a fresh and reliable wiring system. He wired this car with our 20-Circuit Harness Kit and inLINK. The finished product is simple and clean.
He first mounted his Mega Fuse kit in the trunk of the car. This fuse block takes in the primary feed from the battery and distributes power to the front and rear POWERCELLs. Each of these feeds to the POWERCELLs is protected with a 60-amp fuse. Here’s a picture of the mounted Mega Fuses.

Next, he mounted his MASTERCELL behind the dash. This kept all of the wiring going to the switches short. Here’s a picture of the MASTERCELL installed in the car. As you can see all of the wiring is neat and tidy.

The rear POWERCELL is mounted in the trunk. This is powering the fuel pump, the turn signals, brake lights and parking lights. All of the wiring is short, clean and easy to troubleshoot. Here’s a picture of the rear POWERCELL.

The front POWERCELL is mounted on the firewall under the hood. It is powering the headlights, high-beams, ignition coil, wipers, turn signals, parking lights, fog lights and the horn. This is a great location. The wiring is short, the fuses are accessible and it is very clean. Here’s a picture of the front POWERCELL.

As you can see, this is a simple and clean wiring job. It is a very simple car without a ton of electrical functions, but Leverett wanted a reliable wiring harness that would get him the functionality of a late-model car. He did a great job of documenting the harness by creating this overall schematic for the electrical system.
