Yes adds power to the antenna. Reception is pour without it. [ MIGUEL  Feb 20, 2017 ]
Don't know sorry [ GEORGE N  Feb 19, 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. [ JASON  Jul 15, 2015 ]
