Hi I am working on my brothers Disc II. He bought this wiring harness (Part #: 70-9400)

and it didn't fit. Is there another harness or do I need to cut the original harness and replace all of the speakers in the doors to get the aftermarket radio hooked up properly? We are installing a basic CD player. Any info would be appreciated.

 

Not sure which system you are working on, but I'm guessing the Metra 70-1786 would work better for you. How many plugs are on your Disco's harness? On my 01 there are three plugs, two you will need for the new unit. There is most likely an OEM amp under the drivers seat that powers the speakers, you can not use line level inputs to the amp, and will need to use the RCA outs from your new unit. This harness allows you to do this. One other watchout is that the amp gets its turn on input from the blue wire in the harness, and most head units turn this off when you switch from the tuner to the aux, ipod or CD feature. To get around this use the remote amp feature from your new head unit (blue / white wire).

Here is what I purchased when i put my Alpine in my 01:

I have a 04 disco 2 es, iv removed the standerd radio and want to fit a nice dvd /radio head unit. Plugged it in to the standerd conections , powers up but have no sound. I tried a cd player in it and it works fine. How do i get my dvd head to have sound?
