Boy oh boy. I hate to tell you this but there is no park wire on the new unit. The speaker wiring in this thing was so screwed up. Wires changing colors etc. At the oem stereo and at the speakers themselves so must have been oem work. Finally took my time today and traced the wires and hooked it right up & it works as intended.It looked as if a 4yr old had wired it. THANKS for all the suggestions and taking time to try to help. Wish I knew how to post pics on here you would have had a good laugh.
If it was a factory job omg. I have found other shoddy oem things in this Keystone. I thought I had fixed them all but you never know. I suppose they just use what's at hand. Poor quality @ best. I would hope the newer ones are better quality but who knows.
