Hi ive been trying to fix my Barcrest machine it keeps alarming code 84-80 hopper missing, long story short tried replacing hopper, coin mech, mpu5 board and power supply still alarming.

Stupidly ive traced the wires back from the hopper to the white connector that plugs into the payout pins on the mpu5 board, took the connector out and there is a black wire that loops pins 1 and 9 i think and another black wire im guessing is live from the hopper but ive took this out to check and now cant remember what pin it went into?? Can someone post a photo of this connector please? im not sure how to post a photo on here as i have taken a pic of this connector
