the mounting bracket is definitely the same (i know because i changed mine from power to whip), but the only way to know about the wiring is to have a look.
The antenna mast on my 95 4Runner is gone. The antenna motor still cranks every time I start the vehicle, so it still works. I'm trying to decide if I should get a new mast(which I've found at rockauto for about $21) or bail the electric antenna altogether and install a regular antenna.
thats weird, when i got mine at a dealership in calgary they had one in stock. it worked for a while but after a couple of months it started grinding like the old one did so i ditched it for a regular whip antenna.
