I read on one of the CB install sites if i could find the link id give it to you to read that if it shares the same circuit or wiring path as radio harness or in my case the 12V plug it will make noise when it is on. That is what i got when you turn the car on you hear the reving and anytime brakes are applied etx it transmits noise into the cb.
What it was saying basically was that in order to have clearest no noise would be to wire into the fuse box and not have a 12 volt cig lighter plug spliced on it as all the RF i think was the term interferes.

Thinking of getting a fuse tap (which is at end of site) and then running power wire into that and the ground right to metal.
Currently looks like this
Going to try to mount it sideways here
