anyone have a wiring diagram they can post so that i can make up a new one tractor is a diesel thanks for any help if you cant find a wiring diagram use this tried and proven method instead get a camera and take a lot of pictures of where each wire goes write a description of what each wire is on a 3 x 5 card and place the card on the tractor with tape or a paper clip so the description can be seen in the picture make notes attach tags to wire ends and stuff like that and draw sketches if you are planning to make up a new wiring harness anyway a wiring diagram is not really a must have you just need to make yourself a fool resistant trail as you take it apart after you have identified all the connections and wire terminal take the entire wiring harness loose from the tractor and lay it out on a 4 x 8 sheet of plywood so you can spread any branches of the harness out use screws and tie wire or string to secure the spread out harness to the plywood then use a razor knife to carefully open up the harness remove all tape and or loom but leave the individual wires right there untie and retie the tie wires as needed during this process after you have the harness reduced to individual wires you can examine them to see what can be reused and what needs to be replaced work with only a single circuit at a time until you have everything replaced that you need before you begin replacing wires you need to write down the color of each wire on the plywood where the wire ends and where it splices to any other wire if you can pick your way through this post you should be able to make up a new harness but it takes patience and good concentration good luck

If you can't find a wiring diagram, use this tried and proven method instead. Get a camera and take a lot of pictures of where each wire goes, write a description of what each wire is for, or connects to, on a 3 x 5 card and place the card on the tractor with tape or a paper clip so the description can be seen in the picture. Make notes, attach tags to wire ends and stuff like that, and draw sketches of everything. If you are planning to make up a new wiring harness anyway, a wiring diagram is not really a "must have", you just need to make yourself a "fool resistant trail" as you take it apart, that you can follow later. After you have identified all the connections and wire terminals, take the entire wiring harness loose from the tractor and lay it out on a 4 x 8 sheet of plywood so you can spread any branches of the harness out. Use screws and tie wire, or string, to secure the spread out harness to the plywood. After you have the old harness spread out and secured, use a razor knife to carefully open up the harness. Remove all tape and or loom material, but leave the individual wires right there. Untie and retie the securing wires or strings as needed during this process. After you have the harness reduced to individual wires, you can examine them to see what can be reused, and what needs to be replaced. Before you begin replacing wires, you need to write down the color of each wire on the plywood where the wire ends, and where it splices to any other wire. Work with only a single circuit at a time until you have everything replaced that you need to. You should be able to make up a new harness, (after all, the OEM harness was man made) but it takes patience and paying attention to the little details. Wiring diagrams are useful for diagnosing an electrical problem, but I doubt it's benefit for actually fabricating an entire harness from scratch. The diagram might identify most components and circuits, but it might also include some things that are not present on every machine. The method I outlined above could be likened to dismantling a house, one board at a time, marking each board and where it came from, and then using each board as a pattern for cutting replacement boards when needed, and then putting the house back together as a solid, sturdy assembly again from all the boards (both old and new). You would not need to obtain a plan or a blueprint for that if you recorded everything correctly as you took it apart. How well you make up a new harness depends on how well you document the dissection of the old harness. Good luck.
