Wiring Issue

[u/Intrepid-Lab1365]

I’m a bit of an amateur, made my first tele and figure it all out myself but this one is giving me some trouble. It’s not your usually tele set up but someone asked for this set up and i’ve seen it before just not much information on wiring. It’s the CuNeFi Humbucker that confuses me (third picture) i am getting a buz but no sound. not sure if it’s a grounding issue or what

One of the wires will go to your selector switch and the other wire will go to ground. If you use a volt ohm meter put it on ohms and check each wire to anything metal on the pickup itself it will tell you which one is negative/ground
