Need a 1983 xr350r wiring diagram - XR250R & XR400R Apr 10, 2015Here is the wiring diagram from the service manual. Pretty simple. If you're adding blinkers, etc. you may be better off with the wiring diagram of the XL350. Let me know if you need any parts. I'm in the midst of breaking down another '84 XR350 for parts. Good luck.
