Just to clarify: You've removed your Pioneer HU and unplugged the harness from the radio. You've connected a different pioneer HU to the harness that was left in the truck that went to the previous pioneer. Is that right?

Just because the plugs work together doesn't mean the wiring goes to the same thing. You could be sending 12v+ to one of the speaker outputs and not realize it. Do you not have the harness for the pioneer you're trying to install?
