Headunit upgrade with JBL

I have Toyota Prius 2011 JBL system. I am trying to upgrade the audio system. I am unable to find "KD-Z0002" plug anywhere. Is there any other adapter I can use or what are my other options?
Any help will be great.

 

I’m still trying to upgrade mines I need the harness for my jbl system anybody got lucky yet or can help me please

 

"I need the harness for my jbl system"

I am quite sure there is no 'harness', per se, that will allow you to install an aftermarket HU in a JBL Prius. What there is are adapters that will allow you to retain features such as backup camera, steering wheel controls, etc. You must get the adapters that align with your HU (Android vs Apple...). Crutchfield.com sells such adapters and has good customer service. Their website has packages that will fit a given Prius model and Android/Apple application. This is set up assuming you'll buy a given HU from them, but since you already have a HU, you'll need to contact customer service directly for advice. They will get back to you by phone, and most reps are very knowledgeable. Good luck, it ain't a simple matter...(been there, done that).

 

I bought a China Prius specific HU, mfg by Klyde. I bought the canbus adapter the same time I bought the HU. The vendor said there are 2 different harnesses, I sent him a picture of the back of my factory radio so he could send the right harness.

Some cars only need the right harness to use the factory amp. Toyota JBL needs a canbus adapter to turn on the amp.

 

I purchased a similar headunit from ebay and the wire documentation is terrible! I'm seeing 3 RCA outputs instead of 4, i'm assuming one is labeled incorrectly. connecting a reverse camera to it has also been a hassle, it works well sometimes but others it just shows "no signal"
