hey what is needed to put in a aftermarket head unit... when i boutght my disco it didnt have a head unit

 

A single DIN stereo and install harness.
Plug the harness into the trucks wiring, plug the harness into the back of the stereo, put the stereo in the hole.

 

Just put a kenwood in mine it had a aftermarket pioneer already but it sucked. Single DIN is easy get harness that matches plug and play from like crutchfeilds or do it yourself mine was kinda butchered so I cut old wires tidied it up and re-spliced wires its easy sould be color coded...should be

 

see thats what i would have done but the local shop here said there wasnt one and would have to put in a 7wire so i could keep the stoce amp...where can i get the harness i can do the rest easly. this is the first time they ever said theres no harness. THANKS ALOT
