When I got the wire kit for my car for the antenna it doesn't go anywhere because I don't have a power antenna if you do not have a power antenna I would not worry about it I just cut the end of it and left it hanging
[ James Edward  Aug 02, 2017 ]
There is a plug from the antenna that looks like the pointy metal end coming off the white plug. Plug that into the white plug and the one on the adapter goes into the radio. The blue wire goes to the blue wire in the wiring harness for remote power to operate a power antenna.
