How It Works

Testing the Tow Vehicle:

- the Magi-Box takes the place of the trailer - think of it as a miniature trailer!

The seven-way adapter cord is plugged into the tow-vehicle socket and then into the Magi-Box socket. You simply operate the tow-vehicle brake controller, signal lights, running lights etc. while holding the Magi-Box from the drivers seat!

Testing the Trailer Circuits:

- the Magi-Box simulates a Tow Vehicle to operate the various trailer circuits. It uses the trailer battery for it's power source, so a charged battery must be installed in the trailer. Just plug the trailer 7 way cord into the Magi-Box and flip the switches to power up the lights, brake magnets etc. You can now work on these circuits with ease, power up the circuit or disconnect it with a simple switch.

Total parts cost is about $50.00 if purchased retail - you may have many of these parts in your tool box drawer!
