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 aren’t connected due to the fact Idfk what to do with them lol

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

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.
