I can only guess as to what it is never having seen any on any 4Runners nor is it in any of the FSM or Electrical manuals.
I would venture to say it shuts off the fuel pump as a antitheft device. A Keyed electrical Switch
My question is How could the last owner never have seen it.
That could be a real problem if one of the wires broke and the fuel pump did not turn on.
I to am curious now.

80's & some 90's Ford's had this key cylinder in the gas cap area as an emergency trunk release. I would guess hidden power kill switch for the fuel pump due to having the top off at times, and the rest of the vehicle being easy to access for criminals to drive it off.

hmm, that is a neat place for it. maybe its a switch for the fuel pump. that would be useful for preventing theft and also relieving fuel line pressure for working on the fuel system. interesting... i like it.

I appreciate all the responses and suggestions. I've not had time to remove the interior panel but hope to do that tomorrow.
In response to wyoming9 who asked: "My question is How could the last owner never have seen it." To be honest with you when refueling you do not see it at all. I generally stand in front of the RR wheel. The fuel door is always opened with the interior cable release. The keyhole is just barely out of sight during fueling. I had not thought about it in years myself until a friend asked about it while I was fueling up.
This old Toyota is in pretty sad shape. It's more cosmetic than mechanical but it is the only vehicle I have that is worthy of the crappy streets where I live. She has 310,000 miles on her. The rear leaf springs are sprung. The previous owner rolled it twice while off-roading. Right side has a very poor bondo job. I paid $1500 for it in July of 99 and the thing has never let me down. Damn thing goes anywhere. I vowed to drive it until it or I die, whichever comes first. Last week I noticed that the left rear axle bearing has gone bad so I'll be changing that tomorrow.

Still stumped.
I finally got behind that panel and had a look but I'm none the wiser as to what it is for.
There are two wires coming from the back of the key (switch?) that are taped up. The wires drop down below the filler tube moving towards the front of the vehicle. At a point just in front of the lower rear seat cushion the wire disappears into a space I assume is below the floor but above the under carriage. I can shake the wire and hear it rattling around freely in some hidden space in the floor but I can see no easy way into this space to further trace the wire.
No wire is visible under the vehicle but it can be heard easily while shaking it. I have closely examined the engine firewall for wiring that does not emanate or disappear into a factory wire loom but nothing looks out of place. Any ideas for tracing this further would be appreciated.

I would suspect the wires go right to the fuel pump. there is an access panel to the fuel pump sending unit just under the rear seat. I bet the wire pass through that panel under the carpet.

Bring's up some cool thoughts.
I put a switch under the dash of my taco that interrupts the circuit for the clutch start.
So with the hidden switch turned off the truck won't start even if you use the clutch start cancel button. And technically even hot wiring it still wouldn't start it, as the ecu controls that circuit. I use it if I park somewhere strange or am just being paranoid about my 15K build.
