Hello my name is warren I live in Utah this is my first project bike a 1974 dt 175 Yamaha and runs great having problems with wiring I am changing out the headlight to a 20 w one will that affect the wiring at all or do I have to run it off the battery and send all the charging wires back to battery or will it run like the other one off the yellow and white wire the kid I bought it off had all the wires jumbled up and its a mess trying to fig it out
