Sorry Kid, I was replying to you about the nosecone being the same one... but I see now that the wiring diagram looks the same too! No worries, thanks, that will be a big help.
As mentioned I'd removed my fenders - the carriage bolt that attaches the bracket at the axle must be worn and allows the fenders to wobble. I haven't gotten the bracket off yet however. The loader I have prevents me from getting a socket on the front nut as the mount is below the rear axle. I tried to see if I could loosen the loader and slowly back up far enough to gain access without removing the loader completely but that didn't work - it wasn't free enough to stay put while the tractor moved. So I'll have to revisit that at a time TBD...
Anyway, since I have the fenders off I figured I'd clean them up and re-paint. Worked on that a little on the weekend. Found some wasp nests... and some rusty parts. But all in all pretty good. I still don't know where my fenders came from - in a previous post I mentioned they are flat top, but they don't seem to match what should be on a 135. Under the red paint it was yellow, so I wondered if it was the 2135 Industrial version but the part number doesn't match what Agco parts book has for that either. The rear light in the fender had a sort of red film on the back and there was a smaller bulb behind the PAR 36 - so I'd almost assume this was a brake light for something? Here's a photo of the housing that goes on the front of the fender - part number 193026M1. Is there a way to tell what this is off of? I did quick internet searches and can find the part but not necessarily the intended tractor it belongs too.
Also here's the extra bulb / red filter set-up I mentioned:
AND FINALLY - the start of the mess I got in on my garage floor:
