hello, i have a 94 1uz engine and box in a cobra replica, ( i didnt build it ) the overdrive has stopped working, only diagnostic plug i can find is the one on the engine, and theres a little bulb thats been stuffed behind the dash. ( not the neatest of wiring ) from what ive read i can cross connect te1 and e1, and stick a test bulb in w, does the bulb go to earth or battery +
