I hope to either find an unscathed sled or wiring harness and fix that standby mode LED issue. For now I am just happy it works and required very little scary electronics work!
Is the problem with the LED staying on all the time in the car?
Yeah, if your standby LED is staying on all the time, it means that you're somehow *applying* power to the blue amp remote wire instead of letting the empeg use that wire as a signal to turn the amp on and off. Something is wrong with the way the amp remote wire is connected up.
