Pretty basic instructions
Going to hook it up now - will reply by this evening when finished with truck work as to how it sounds.

Honestly - thats the best reason I came up with too. Seperate out the draw from the main harness. But then I got to thinking - well if I am not using a cigarette lighter ..... and another 10% of the circuits ..... and the radio already has a dedicated 20A circuit ...... then .... shouldnt need a relay
Which led me here.
