Yamaha ybr 135, speedometer change

[Gemstone90]

Hi, first time post, looking for wiring advice. 

 

I'm having to change my speedometer, from the analogue and wanted to go digital. However, thought it would a simple switch, but obvs not. 

 

My problem is I have less connections on the new speedometer than connections I have on the bike. 

 

I'm pretty sure I'm going to have to split the wire for 'clock' to make it fit, but wanted to make sure. Electrics are not my forte

 

Any help and advice is appreciated
