Hi, I’m trying to find the correct full wiring loom diagram for my 2002 Yamaha DT125R DE03 / 3RMM (VIN starts JYADE031) with the 14-wire CDI.
I recently bought a replacement loom from eBay, but only some of the connectors match up properly. A few plugs fit perfectly, but others are completely different, so I think the bike may have mixed-year electrics or swapped parts from previous owners.
The bike has definitely been messed around with over the years.
I’ve already checked the Haynes manual diagrams, but they don’t seem to match this loom or CDI setup properly.
I’m trying to identify:
correct CDI wiring
YPVS connections
regulator/rectifier wiring
stator and pickup wiring
sidestand relay wiring
differences between DE03 / 3RM / 4BL looms
The bike still uses the late-model 14-wire CDI setup.
If anyone has:
the proper factory wiring diagram
or knows the differences between the late DT125R looms
it would help massively.
Thanks.
Oliver
