My ds far fan is not kicking on. I have not hear it at all. I just got this bike a couple weeks ago. Also my headlights don't work. Have been unplugged and don't know where to plug them in. Also brake light don't work. I even installled a new led light. Nothing

 

check the fuses under the seat for all the items lacking power. You said "headlightS", but the 2001 only comes with the single center mounted headlight. Are these aftermarket? Are these baja add on's from another year? If these are additional lights, you won't have a plug in the harness, and you will have to do some splicing. The best way is to use a relay to transfer the power and just tap into the headlight switch to turn it on. see here: DS 650 Accessory Lighting Wiring Detail
