I just had a look at some yamaha manuals and their routing diagrams aren't the best, but the side notes do describe how to fit the cables, to left or right, under or over things...

I think pay sites for manuals are generally ok. If it says ER I'd believe it. Partzilla tell you what other models a part will fit, babbits doesn't do that. You have the electrical component positions(hopefully correct) but you don't have a routeing diagram for the loom.. that might help. The routing diagram and the electrical component positions should solve most of it, then you start looking at wiring diagrams for pairs or triple wires of the colours you have left over to see what they might be. If the positions or the routing don't seem right/possible then you might need a different manual, but there should be a manual that has that right. That sort of thing gets carried over from year to year for a long time.

Yes the information is all there all the componets and part numbers,which is a great help, what i was referring to is, i would like to see a drawing or photo of the bike frame in the manual of exactly where the componets are located on the frame , that would be very handy when you get one that the previous owners have yanked everything off, and thats usually what i get. I guess you cant have everything!

The manufacturers service manual, well the japenese ones anyway, always have all the information you need. It's best to read right through the manual familiarising yourself with the sections and what's where. In this case the manual will probably have a diagram showing the main electrical components position on the bike. It will have a routing diagram showing exactly where to route each branch off the main loom. The routing diagrams are often in the form of plans and side views and it takes a while studying them to get the three dimensional view. And there should be a wiring diagram showing wires and plugs. The three different diagrams are likely in different sections of the manual. The real trouble here is that we don't have the exact manual. It should be possible to find a wiring diagram that will have the same components and wire routing, but probably different colours and plugs. I'd refer to partzilla to see what other models the voltage regulator, stator and cdi all interchange with. If there's a model that shares all those parts, then it likely shares the kill and key switch as well, and the wiring diagram will probably work with your bike.

I understand your frustration, i looked for the same harness layout when i was rewiring the Big Bear, never found exactly what i was looking for. The closest thing that helps somewhat, is the cable routing section of the manual. It shows a diagram of the frame and where certain componets are located. A little help but not much. What i ended up doing was studying the wiring diagrams to the point of having them memorized, wire colors components and wiring, using the cable routing diagram as a guide, it does show a few electrical components there. Looked at all the U tubes i could find where they were working on the harness and just pieced all this information together to figure it out. I have not used Clymer or Haynes much, but sometimes they have more practical information there and maybe a diagram, that will help, im not sure. I looked a little havent really found a manual for yours yet, mostly i find the one for the 200, yours is the 350, right. So i am still looking i will let you know what i find.

great news just found the leak on carburetor and again thank you all for your precious help, bob
