"Y-adapter" that will let you combine both antennas into one connector (reverse splitter, essentially). One of the antennas has a non-standard connector so you also need an adapter to convert it to a standard interface.
The other radio problem people have is the 4Runner also has a signal amplifier in the antenna chain. If your radio harness doesn't include a turn-on lead for the signal amplifier, you'll get poor to no reception.
Searching the forum should turn up multiple discussions for all of these topics and more. After 17 years, if it can be done to the 4th gen, someone's already done it and has the t-shirt to prove it.

Excellent information and thanks.
I know, right?
That's one reason I love my 4Runner so much.
In between my old Pathfinder Sport and the 4Runner, I had a Rodeo for a bit.
Literally near
nothing on that car as far as DIY 'been there done that' information.
With the 4Runner, I don't think I've ever run into something that wasn't documented a hundred dozen times over.
Interesting about the antennae signal amplifier, that answers a question I had read about somewhere else.
That after putting a new receiver in, their signal was crap no matter what they tried to do, splitting, y-cables, they still had terrible reception.
The whole shooting match arrives Monday from Crutchfield.
Receiver, amp, front and rear speakers, and 10" sub.
