Q
If I'm installing new amplifier(s) and running all new speaker wire to added amp do I still need this harness for bypass of factory amp? Or should I use a standard "non" factory amplifier harness.

What are the three extra wires for?

Power, ground, and memory. The other wires by- pass the amp for the speakers.

Blue is the remote wire the red is the acc wire and the orange I believe is the Illumination wire
