Can anyone tell me where to access the backup wire is on a 2002 Toyota Tacoma extra cab 4X4? (engine is 3.4 liter V6)

I realize I can access the wire in the rear of the vehicle by tapping into the brake light wiring harness, but I'm hoping there is an access point in the cab or dash somewhere.

Bump...

It's been 5 weeks since I threw the question out there and not even a nibble...
