You can absolutely install an aftermarket 7-way, to use a brake controller on your 2005 Infiniti QX56.

In order to by-pass your current broken 7-way you will need to use the Vehicle Wiring Harness Kit # C59496. This will splice into your lighting and provide a 4-way connector. You will then use the Universal Installation Kit for Trailer Brake Controller # ETBC7 to adapt the 4-way into a 7-way.

This will provide you with a functioning 7-way to use the Redarc Tow-Pro Liberty Brake Controller # RED24FR. You will also need the Universal Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers # RED69FR since your brake control port does not work. This harness will splice in to the wiring, instead of using the port.
