two big wires are inhibit. There should be a pair of small wires also coming from the inhibitor switch- feed and return for the reversing lights.
The overdrive solenoid is inside the 'box- follow one of the cables into the box through a grommet (poss. black wire).
Is it 4x4? they have a temp sensor on one of the cooler pipes, and a sensor for 4x4 in the transferbox. Also the speedo is electronic on some versions. - (#1424) David Miller, 15 Nov 01
