It's pretty easy.
All you have to do is remove the radio, and cut the remote antenae lead and wire that to your switch. It's that simple.
Which wire it is for you, I don't know. If you have a stock head unit you can find the wiring code in a Helms manual, or you can go to your nearest dealer and they can photo copy the wire codes for you. I don't know if they'll charge you for it or not, but they've never charged me.
Hope this helps.
