Just bought a Pioneer DEH-P8400BU along with the modifry adapter. I wired my DCI and adapter harness to the pioneer harness. I installed everything and my HU will not turn on. I put my stock HU back in and it wouldn't turn on as well.
I checked my radio fuse(15A) and it was blown. I took out the Washer Motor(15A) and placed it in the #19 position of the radio fuse.
I connected the OEM radio and it works. I disconnected the cables and connected my Pioneer but unfortunately it will not turn on. Is there any sort of troubleshooting I can try to get it to turn on and work?

DELETE PLEASE. If possible... problem resolved. I forgot to put back in my fuse from the radio that I took out -.-
