Fitting Instructions

The good news is Fender Bullet Mustang is one of the more simple guitars to replace the wiring harness, because the wiring harness is attached to the removable pickguard and control plate.


  1. Find somewhere safe, dry and secure to place your Bullet Mustang guitar while you work on it.
  2. Remove Strings.
  3. Undo the screws that hold the pickguard to the body. Do not undo the 4 x pickup screws by mistake.
  4. Undo the 3 x screws that hold the control plate to the body.
  5. Carefully lift the control plate up and cut all wires from the body to the control plate closest to the pots. These are a couple of ground wires (normal black is colour).
  6. Now lift out the pickguard and the control plate together.
  7. Put the guitar safely out the way for the time being.


  1. Working on the control plate and pickguard, cut the 4 x pickup wires from the back of the 3 way switch and pots, leaving the wires as long as possible.
  2. You should now be able to remove all the wiring harness components from the pickguard and control plate, leaving the pickups in place.
  3. If you are replacing the pickups, this is the time to do it.
  4. At this point you may want to clean the front of pickguard and control plate where the old pots and switch have been.
  5. You will need to check the size of the holes for the pots as on some pickguards they are drilled small for cheap electrical components. If they are small, the best way to enlarge them to 10mm to fit CTS pots, is to use a round file.
  6. The pickguard and control plate are now ready to fit the new harness.
  7. From here everything is in reverse using the wiring diagram below.
  8. Fit the new wiring harness into the control plate and the switch into the pickguard.
  9. Solder the 4 x pickup wires to the switche (refer to wiring diagram).
  10. The pickguard and control plate are now ready to go back into the guitar.
  11. With the pickguard resting next to the guitar, solder the ground leads to the volume pot. (refer to wiring diagram).
  12. Fit the pickguard and control plate back into place, but don’t screw it down yet.


  1. Plug the guitar into an amp and with something small and metal you should get a response from the pickups by gently tapping the pickup poles/posts. – Or you may have a Multimeter!
  2. If Everything is working, screw the pickguard into place and re-string.
