Do you know what model Cardinal you have?
As others have stated, if it is the converter you are seeking, then it's many times located below or very near the power distribution center. However it can be further away on some RV's.
Here is a link to a thread, where we discussed and showed some pics on where to look for the converter (If that is what indeed you are seeking)
No 12 volt or hvac
