Default No fuel pump prime.

Found out my fuel pump relay was jumped to constantly run, took jumper off black/white to brown and i lose prime. Ive verified tip sensor is good and kick stand sensor, swapped relays and no luck. Confirmed green wire on pump is recieving ground odd thing is. My brown/black wire has 12v from what ive gathered that is the fuel reserve wire. My brown doesnt have 12. 12v on brown black cuts off with kill switch. Cant figure out if someone has crossed a wire. Any input? Or can anyone provide me with the direct wire position on relays. Last owner took connector apart…. See pictures attached. The bikes wiring is a damn mess, found out they also put the wrong ecu in it aswell. Ive owned it for 2 months im just trying to put it back the way its supposed to be. I appreciate all yalls input
