I am installing a stereo in my Dart. It is a satellite radio and there is a component, the de-scrambler box, that the instructions say "attach the yellow power line to a "constant power source". It says to hook the head unit power to the source controled at the accessory position of the ignition switch.
The head unit was easy...just used the power lead from the existing original am/fm radio.
Where should I grab power for the other piece???

Cigarette lighter? Any constant hot would work, E bodies have two open terminals on the fuse box, one is constant, the other switched.... I don't recall if A bodies have that or not....

The term switched is typically used to indicate power on with the key in run or accessory position, power off in the key off position...

EXACTLY
But furthermore, how much power do you need for those two lines? If this is a fairly large stereo, probably the "constant 12V" lead is the "main power" to the stereo, and it's important that it be heavy enough and properly fused
The "switched" lead is probably a control lead. What about your AM radio connector? You still using it? It will already be marked "radio" on the fuse panel, so that makes good sense.
The connector should have two leads. One is for the lamp, the other is "switched 12v in accessory"

Hey Darius, this is Mike A. here. I'm up at Danans place for the weekend. I have to say real muscle car guys don't run radios in true muscle cars. The sound of the engine should be music enough!
Normally the car sound is fine but 400 miles to Spring Fling I'm gonna want some tuneage!
I hooked the whole thing up, took most of the day Sat and all day today (8am-just now) and it won't power up. What I did was take the lead off the radio because I won't be using that anymore and use that as a power source. The "brain box" for the satellite had a yellow line out of it that said "battery" on it but it went directly into the din plug in the back of the head unit. There was a splice on it but I was thinking it was the power to the 6 disc changer I had in the truck I took this system out of. Since I am not using the changer I thought I didn't need to run to any other power source. I did NOT hook up the lights (orange line to radio) to the head unit. Would that cause the whole thing to not power up??
I grounded the head unit to the dash frame and the "brain box" to the package tray (mounted in trunk).
I am no good at auto electric and it just showed. Pisses me off too because I can wire a house blindfolded, 3 way, 4way switches, 220, you name it.
