Sorry got a bit busy this evening, but I d not think it really deserves a diagram,
If you are grounding the motor on the chassis, then you only need one long heavy lead (Starter motor size) from the battery pos terminal to an isolater switch best mounted through the back of the cab or similar with the removeable key switch in side, from there to the motor and this is the lower right hand bolt, with a good crimp on or solder spade terminal on the wire, all you need now is a board or similar with two sturdy push buttons, one marked "up" one "down", wire one side of each button with 2.5 mm flexible cable together and take it to earth/chassis/ground, the other side of the "Up" button goes the short lead on the left in the picture, the other side of the "Down" button goes to the longer lead on the right, no need for relays unless you plan to have a long wander lead for the button board, any questions please get back, Rick
