Have a pedal, it was rewired to run on an auxilliary cable.

Would like to rewire it to run on a 9 volt.

Anyone dealt with similar?

Was any sort of transformer added to the pedal, or was it just wired to use an auxiliary power source with a transformer brick at the outlet? If it is the latter, then you basically just need to solder a 9v battery connector to the wires.

This is what I assumed. I will take a picture and post what I am looking at later.

interesting

Might take it somewhere if it is too complicated, don't really have the knowledge or the tools.

The pedal is a Electro Harmonix Big Muff.
