Disco 2 sound system

.

Hi, unless you are an extremely skilled electronist you'll not be able to rewire the audio system cos it's about too much difference between the vehicle's main harnesses, all you can do is to identify the proper harness for the system you want to retrofit and change the main haarness which involves removing the whole dash and central console, you need the proper one of the harnesses listed in the following link http://new.lrcat.com/#!/1232/36532/36727/2796/36798 or remove the main harness from the donor vehicle and transplant that into the actual one... wiring in the speakers is doable with less hassle
