ProtonPal

Tap the ProtonPal power wires

Take the two-pin JST-XH cable with the red and black wires from the ProtonPal kit. Slide the wire-tapping connectors over the black and green power wires identified in the photo.

• ProtonPal red wire with the tap → factory green wire (positive)
• ProtonPal black wire with the tap → factory black wire (ground)

Use pliers to close each tap assembly so it makes a tight connection to the factory wire.

Connect the activation and firing controls

Take the two-pin JST-XH cable with the blue and yellow wires. Locate the two control wires shown in the upper-left area of the annotated photo. The factory wires may be tightly bound, so carefully separate them without pulling on the PCB connections.

• ProtonPal blue wire → factory blue wire (activate)
• ProtonPal yellow wire → factory brown wire (intensify / fire)

Attach the wires with the supplied crimping connectors.

Connect ProtonPal wiring to the taps

Locate the two JST wiring assemblies with spade terminals. The assembly with the red and black wires plugs into the ProtonPal board’s 5V IN connector. The other assembly plugs into the yellow HC BRD connector on the board.

Attach the spade terminals to the wire taps as shown:

• Red wire → green tapped wire (power)
• Black wire → black tapped wire (power)
• Blue wire → blue tapped wire (control)
• Yellow wire → brown tapped wire (control)

Push the spade terminals firmly into the taps, but support the taps while doing so to avoid breaking the wiring.

Connect the speaker output

Clip the blue speaker wires from the bottom of the factory PCB, or desolder them. If desoldering, heat the hot glue first so the wires can be removed without stressing the board. If you clipped the wires, strip the ends.

ProtonPal has one speaker amplifier output. Choose one of these options:

• Connect one blue speaker-wire pair directly to the ProtonPal speaker-out terminal.
• Connect the factory speakers in series: connect one speaker’s blue wire to the other speaker’s blue/black-striped wire, then connect the two remaining blue and blue/black-striped wires to the ProtonPal speaker terminal.

Important: Insulate or secure any unused speaker wires so they cannot touch another conductor.

Optional: retain the factory volume control

To keep volume control from the factory wand, clip or desolder the three-wire volume-control cable identified in the photo. Strip the wire ends if you clipped them.

Open the three-position screw terminals on ProtonPal with a small flat-head screwdriver if necessary. Insert the wires from left to right in this order:

Tighten each terminal and check that no stray wire strands are exposed.

Optional: install a MicroSD card with sounds

ProtonPal includes basic lower-quality sounds internally. You can replace them with your own sounds by installing a FAT32-formatted MicroSD card. Use WAV files up to 44 kHz, 16-bit.
