I'm looking to install a Boss style PSA jack to replace the original positive tip 2.1mm jack. Do I just flip the wiring on the jacks? I.e., tip (+) wiring (on board w/ resistor) now goes to the barrel wiring of the Boss PSA and the sleeve (-) of the 2.1mm now goes to the tip of the Boss PSA?
Are there any changes to the wiring that goes to the lugs of the input/output jacks?
