Pioneer 4100DVD
Edit, in case anyone else happens to stumble upon this in the future... :
YEL is Battery/Constant on Power
RED is ACC/Switched Power
BLK is Ground (obviously)
The other colors can be pretty much found by balance/fade.
Hey guys I got this thing second-hand without the manual and I tried pulling up the manual online but it doesn't show anything in regards to the actual wiring of it...
I have what seems to be 2 power lines coming out of the scosche adapter, a red and yellow... also a red & yellow going in to the headunit's OEM molex.
I was just curious if anyone has had experience installing Pioneer units if both are required for power, or can I crimp the yellow off and only use the red power line? Not sure why they have 2 power lines running end to end...?

You need both.
The red constant battery power is used for keeping the memory and it is the heavy power source.
The yellow is used to signal the head-end and its amplifier on and off and it connected to the ACC accessory power which comes on and off with the ignition switch.
If you connect both to battery you'll have to shut things down manually when you turn off the car. A dead battery is what you risk. If you connect both to the ignition switch controlled power you'll lose the memory settings on the radio every time you turn off the car.
Connecting a high-power external amplifier to the ignition circuit is also bad/hard on the ignition relay and wiring not designed for the extra 40-1 million amps worth of current.
