since i will be running bazzaz i guess there is no need for me to pick up a harness. just wanna make sure im getting it right when i say almost every track/race bike out there has "hacked up" wiring harnesses. just find it hard to believe there isnt one aftermarket plug and play piece. thanks for the help!
If I am reading this correctly I think you are misunderstanding everything. The YEC harness is to be used for racing, it is wired differently than an OEM harness and doesn't use the front lights sub harness and some other things you will need to ride on the street but it is only to be used with a YEC ECU.
The Bazzaz unit is a piggyback controller and plugs in between the injectors and some sensors. The Bazzaz unit is plug and play but you have to plug everything in.
