Hello we purchased a gear indicator from Amazon for my wife’s 2008 Honda CBR 125 that supposedly is plug and play and plugs into the bikes diagnostic plug. We’ve looked under the seat and under the steering wheel and can not find this plug. Does anyone know if this bike has a diagnostic plug and where it’s located? If this bike doesn’t have a diagnostic plug is there another way to install a gear indicator. Thank you for reading this post and your time
