hi there new to this site but from what i can see it seems to be the best !!! so anyways heres my prob i just got a trx 400fw hasent ran in about a year so got it for a gd price as its a none runner . so started to have a wee look for probs and found that the ignition wires on the barrel were snaped all off them so pulled the barrel out and im left with 4 wires red black red with black stripe and pink !!!! so i wired the red and black got my neutral light on hit the start button and away she went and seems to be running great . but now my only prob is what are the other 2 wires for ??????????? i dont think the battery is charging do these wires have anything to do with the charging side off things ???????
