Thread: GMS-7Z No accurate diagram

    GMS-7Z No accurate diagram

    Could someone help me determine the wiring for the GMS-7Z? It has 2 humbuckers, 1volume, 1 tone and a 3 way switch. There is one wiring diagram available from Pitbull with these specs, but it shows 2 leads coming off of each humbucker, whereas I have 4 (red, green, black, bare).

    Also, along the way in shipping or I just picked the harness up the wrong and wires broke because the solder joints were so brittle. I've got a few wires disconnected. Here is a quick drawing of where it's at currently: https://imgur.com/a/56zfjfe

    Thank you in advance to anyone who can help!

    I was mistaken, there are actually 5 wires from each humbucker; red, green, black, WHITE and bare

    Went ahead and tried to complete the diagram with a little reading. I have no clue what the Pitbull factory used for colors however, so any help there would be appreciated too:

    Black: Start of North coil
    White (orange in diagram): Finish of North coil
    Green: start of South coil
    Red: Finish of South coil
    Bare: ground

    Red and whites are soldered together, taped
    Greens are soldered to the bare wires
    Bare wires are soldered to the back of the volume pot
    Black wires are soldered to opposite sides of the switch

    Other than that, the Pitbull wiring diagram should be correct, though I received with an extra ground running from the volume pot to the input jack.

    Hi altizerc2196,

    I think that looks OK.

    I assumed "the extra ground" was to ground the bridge - but that is covered in your diagram! Maybe in could be used to ground the switch?
