I am installing the aem tru boost controller and a oil pressure gauge and was wondering: Intructions stated to use a switched fused +12v source, I am assuming they are referring to ACC. is this correct?
secondly, I try to avoid cutting any factory wires so I was planning to run all the gauge and controller wires to my aftermarket cd player harness, would that be a good location?
any help would be great.

your correct on you assumption of the power source however ganging them on that one circuit is foolish!! if you have a cig lighter use that circuit and throw the element away....

 

Ditto on using the cig lighter for 12V switched. It's the easiest to use and is exactly what you need.

 

so just run one gauge off the radio harness and the controller off the cig outlet. thanks
