Also I think your white wire needs to go to z33 and z33 is programmable in menu as a bell tamper , z33 normally has the resistor on it in series so like white wire connects to resistor and then resistor goes into z33 , resistor mostly goes in bell , but your in bench DIY unit won't matter
Been a while since I did this , isn't D- , zero volts so that's where the black would go ?
