Hello. I have searched, but can't find an answer. 2000 Impala gold edition. I bought a Scosche harness to relocate oem radio to trunk. Wired up Sony radio to harness, and sounds great. But it doesn't turn off when I open the door like the original. It will turn off after about 30 sec and then back on if door is opened. Can turn it on and off manually, but I thought it would work with RAP like the stock with this harness. Do I need to run red power to rap at fuse panel? Not sure why its not working. Thanks for any help.
