Motorcycle Repair: DT3 1973 yamaha wire harness, dt360, dt250

Question
Theres a guy selling a oem wire harness that is for a DT250 with a part #445-82540-22 and my DT3 wire harness part number is 308-82590-20. Are these interchangeable? It's hard finding a harness for this old bike I'm restoring and this harness for sale is cherry.

Answer
Jon, this may be beyond my experience I used to own a 1974 DT360 and had some bad luck and had to fix the wiring and the folks at Yamaha said that each year they change some things even if its  the same model bike.Ihe harness might work but sometimes the connectors are different trying to make some problem go away so they say. You may have to modify the connections some to get all components to work.
