so I'm about to order a new double din radio to replace my factory one. Do I need to order a harness with it or anything or will it just screw in to the factory spots some how? I was gonna order a Pioneer FH-X700BT
*edit*
I may have solved my own issue. I just found this thread on jeeps. I'll post the link in case anyone else has the same question
