    I haven't found the time to sit down and get on with this, I'm hoping this week, I'll document the process, and sure I'll have more questions :)

    Hello there, so I took the time to follow the procedure and change my pickups.
    Problem is I have no sound coming out of the guitar now. I think I followed the diagram religiously.
    Can anybody spot my mistakes?
    thanks for the help!

    Could it be that the red isn't the hot wire and I should swap the red and white?

    Not being able to see all of the documentation, my instinct would have been to run the red and white as "hot, grounding only the bare wire. From the picture, the white appears to be grounded.

    Thanks for the answer: the kit is the one : https://www.allparts.com/EP-4146-000-Wiring-Kit-for-Gibsonreg-SGreg-Guitars_p_1372.html
    I tried to tie together the red and white and ground the bare wire only, still nothing.
    When using s multimeter set to up to 20k ohms, Between the red and white I get a ~7 reading. That should indicate that the pickups work?
    I followed the diagram and went through it over and over, I am really stuck...

    The ground wire to the output jack is missing. You might want to move that ground wire coming from the bridge away from the switch so that it is not crossing over the top of those contacts that go to the hot wires on the pups.

    Use below for reference...

    Yeah, I forgot we were dealing with P90s. Check the connections at the jack and then at the switch carefully to make sure you're not shorting the leads with the shielding. If that's all good, I'd say you need to see a tech.

    Thanks for this, I think the wire with the metal shielding is messing things up, I'll get some other wire tomorrow.

    Thank you all for the help and support!
    After redoing the wiring and carefully ground everything properly, all works as it should!
    I had to investigate as my neck pickup volume wasn't going to 0 but somewhere around 50%. This has been a learning process and learning by making mistakes is definitely the best way.
    The job isn't the prettiest but it works so I won't complain.
