First check for correct wire color connections. The following link states the ZJ wire color and function, match to corresponding function on radio.

Im assuming this is an aftermarket head unit? Did you connect the amp ground wire to it? I read somewhere that if its not connected, no sound. I never had this issue tho as all my vehicles are still rockin the factory tape decks.

as far as I know no because the amp recives everything from the ecu. The ecu has wired that go to the headunit which arenít connected due to the fact Idfk what to do with them lol

Shouldn't be anything ECU related to the stereo/amp wiring.

Take a look at this:

no clue. As far as I know the ecu sends signal to the amp. The ecu has 2 wires that go into the head unit. If these wires are taped together the vehicle stops running

Are you thinking BCM? That would possibly make a bit more sense.

Even that doesn't show anything.

PCI bus is for the CD changer and or steering wheel controls. If you touch the wires your probably grounding something out or causing a short.
