Default 2 quick SI questions

I have repackaged one of my SI T-amps but am having a couple of problems:

1. LED not working even though I have 12 volts on the wires going to it. New LED time, or did I miss something?

2. I don't want or need a volume control. To simply go directly from RCA's to the board, which of the white wires do I solder to the RCA's? Right now, if you look at the board from above, with the edge connector closest to you, the two red wires (to the power switch) are on the left, the next two white wires are not connected, the middle white wire is connected to ground, and the two white wires furthest right are connected to the RCA's. I have power on the board but no sound. Am I using the right wires for inputs?

1. check for correct polarity and if you have 12v, you need a 1k5 resisistor in series with LED...
2. the 2 white wires next to the red wires go to the rca's.
