The Wireless Module is located on the Bottom of the laptop,http://www.irisvista.com/tech/laptops/ToshibaP25/disassembly/big/Toshiba_SatelliteP25_03.jpg
The top card to the left. (With the red arrow)
White Wireless Antenna wire, and a Black Wireless Antenna wire.
You can see which terminal the White wire connects to. Leaves the other terminal for the Black wire.

The Wireless Antenna wires attach to the Wireless Module,http://www.ebay.com/itm/WIFI-WIRELESS-PA3299U-1MPC-Card-for-17-Laptop-Toshiba-Satellite-P25-/170900245815?pt=LH_DefaultDomain_0&hash=item27ca72cd37
Looks to me the White wire to MAIN, and the Black wire to AUX.
The Wireless Antenna wires then thread up through a cavity (Hole), in the laptop body, and go through/by the Right Hinge.
From there they go into the Display Assembly, and connect to the Wireless Antenna,http://www.irisvista.com/tech/laptops/ToshibaP25/satP25_LCD.htmhttp://www.ebay.com/itm/Toshiba-P25-Satellite-Laptop-WiFi-ANTENNA-K000006070-/220547282983
Scroll down, read the description.
The Wireless Antenna wires route through CHANNELS, and LATCHES.
The Wireless Antenna wires MUST go back in the SAME routing they were originally.
Failure to do will cause the laptop to not go back together correctly, and can cause damage to the Wireless Antenna Cable. (Wires)
