Do all aftermarket head units come with ISO harnesses

Hi, I am still trying to decide between a Pioneer, Alpine and Kenwood. Does anyone know if the head units (CD receivers) sold by these companies come with an ISO harness.\

I have already ordered the harness to go from the car's harness to an iso connector. I just want to make sure that I do not need another harness that goes from the iso to the radio.

What is an ISO harness?

ISO harness has an ISO connector, which is a standardised connector to allow all head units to connect to aftermarket car specific harnesses. Its to prevent having to cut and splice and tape wires.

i installed an alpine HU to my car a few months ago, and need to buy 2 harnesses.

alpine > ISO
ISO > mazda

Thanks for that. This backs up the impression I have been forming that Alpine units need a harness. Is the same true for Pioneer or Kenwood?

Yes it is. Each company has their own standard that you need to take to iso so you can go iso to Mazda

I wish the previous owner of my car had used a connector harness. My wiring is a mess under the dash. Between the radio and alarm I removed about half a mile of wire when I replaced my dashboard but in hindsight I wish I had purchased an un-mutilated loom.
