Knowledge Base - Info:- Brake & Fog Lamp Wiring Diagrams.
Our rev 4 had the inner two lamps wired as fog lamps with higher wattage bulbs. I fitted dual filament lamp holders (from any Toyota stop/tail) and wired the side light across from the outers so we had 4 tail lamps. I then wired a 5 amp diode from the outer brake lamps to the inner ones (having connected the two inners together). I also wired a 5 amp diode in the line from the rear fog lamp switch to the inner brake lamps.
When the brakes are applied, all 4 lamps light brightly, when rear fogs are on the two inners are on all the time and the two outers act as brake lights.
Heres a couple of wiring diagrams in PDF format.
