After having difficulty finding clear images easily showing which wires should be jumped, I have taken these in case they will be useful to others.
This is the female plug of the factory Bose dual amp assembly from a 2001 LS with the single din Bose system.
Completed bypass plug.
And each jumper in order to accurately show them... in case of color blindness or the such.
It's not needed to keep both wires from the two wire terminals, I did so to keep from having any cut wires. I de-pinned the now unused wires as well.
I want to also include this image swiped from M dot net. This is a simple diagram showing which wires to jump, but it is from the male side/harness side of the amp connector.
