No pwr to radio in acc position

[Fleetranger]

Am new to Rangers and just got a 2011 w/a oem am/fm radio. I noticed that it only works when the key is in the on position. How do I move the pwr lead from the on side of the switch to the acc side?
Tnx much

I think you have stumped everyone - me included.
Lemme look at some stuff...

Here is a link to the service manual for your truck.
