Getting Ready

  • 1) Check the fit

    • Check the Pro-Wired Electronics will fit your Les Paul.
    • You can print the below diagram as a guide. Be sure to print this to 100% scale.
    • Ensure - control holes are 3/8" / 9.52mm.
    • Ensure - Knobs are US Spec 24 Spline models. Metric or Import models will damage your harness.
    • DOWNLOAD LES PAUL LAYOUT DIAGRAM

  • 2) Find your diagram

    • Find the appropriate install wiring diagram above.
    • These diagrams are specific to each product so ensure you use the correct one.

  • 3) Identify your pickup wires

    • Checkout our guide for popular pickup builders below.
    • For those not listed, you can use your pickup builders install manual to identify the correct wires.
    • PICKUP COLOUR CODES

Remove Your old Harness

  • 4) Clip the wires

    • Clip the pickup, ground output jack and switch wires from the harness.
    • Cut these cleanly, and as close to possible to the existing wiring harness, to ensure there is enough length to reach your new Pro-Wired Electronics.

  • 5) Remove knobs

    • Gently remove your knobs from the harness.
    • Undo all of the existing mounting nuts for the control pots (potentiometers), switch and jack. 

  • 6) Remove old wiring

    • Remove the pots, jack and switch from your guitar and set them aside.

Install Your New Harness

  • 7) Set nut height

    • Set the nut height on your control pots.
    • The correct height will depend on your cavities depth.
    • As a guide set the nuts around halfway for an Epiphone® or just a touch off the harness for a Gibson®. 

  • 8) Install the switch

    • Feed the wire through the body so the cable reaches through to the control cavity.
    • This should be pushed through, not pulled. Pulling can cause the cable jacket to slip off.
    • Install the switch & secure with the hardware provided.

  • 9) Install the jack

    • Secure your new jack to the jack plate.
    • Feed the cable through the jack cavity.
    • Fix the jack plate to the body.

Install The Wires

  • 10) Prepare the wires

    • Strip pickup and ground wire insulation leaving 6mm (1/4”) of bare wire.
    • Be Precise
    • Twist loose strands of wire between your fingers to create a firm tip.

  • 11) Press & hold connector button

    • Use a fine screw driver to press and hold the connector button above the wire slot.
    • For a full guide on using the solder-less connectors, check below
    • FULL CONNECTOR GUIDE

  • 12) Insert wire & release button

    • Insert the wire to the correct slot at a 45° angle.
    • Release the button and the wire should hold firmly.
    • Test the wire by giving it a gentle pull before moving on to the next wire.

  • 13) Insert ground wires

    • Insert ground wires to the screw down connectors and screw down to secure.
    • These connectors can handle multiple wires.

  • 14) Enjoy...

    • Re-assemble your guitar with knobs and back plate, and enjoy...

A Guide For

Vintage Braided Wire

ObsidianWire Pro-Wired Electronics for Les Paul® are designed to also work perfectly with vintage style braided shield cable. For these pickups:

  • Inner core wire = Hot
  • Outer Braid = Ground

Strip the outer braid (ground) from the end of the cable, to ensure good separation from the inner core (hot).

The entire cable can then be fed through the screw down ground connector.
