Electrical help
 

Hello. Wonder if anyone can help me with my chinese 150cc atv with 150cc Lifan engine 162fmj with manual trans,. Bought with new wiring loom. Nothing happens when I push the start button. Starter relay signal cable does not have 12v. The atv has no switches on brakes, or clutch handle, but I would guess the wiring have connections for that, that is not connected, and that is the reason why it wont crank. It also have a sensor for the gear, but I am assuming its for å green light only? Solenoid is working.

Can anyone tell me how these safety interlocks works..
