Install the red wire in hole 2 and solder it. Install the orange wire in hole 3 and solder it. Trim the
soldered wires with diagonal cutters. Set aside this wired board.
Brightness pot board
Find the three 7” long green, blue and violet wires. Strip 1/4" of insulation off the free end of each wire.
Tin the bare ends of the wires with solder, being careful to remove any blobs.
Mount the kitty board with 504L pot in the vise. Insert the violet wire into the hole marked 1, with the
insulation on the pot side of the board. Solder it from below/front.
Install the blue wire in hole 2 and solder it. Install the green wire in hole 3 and solder it. Trim the
soldered wires with diagonal cutters. Set aside this wired board.
Focus pot board
Find the three 8” long brown, red and orange wires. Strip 1/4" of insulation off the free end of each wire.
Tin the bare ends of the wires with solder, being careful to remove any blobs.
Mount the remaining kitty board with 105L pot in the vise. Insert the orange wire into the hole marked
1, with the insulation on the pot side of the board. Solder it from below/front.
Install the red wire in hole 2 and solder it. Install the brown wire in hole 3 and solder it. Trim the
soldered wires with diagonal cutters. Set aside this wired board.
Position pot connector
On each of the four pot boards, twist the three wires around each other to form a twisted triad. See the
picture below. Bend the wires down around the pot board so that they exit parallel to the board.
Find the small 6 pin header block. Orient it so that the large holes are facing you, and the small slots are
at the top. This places pin 1 at the left end. You will insert the little terminals into this block with the
tiny tab facing up. The pins need to be inserted with the pin aimed up slightly so that it will slide into an
internal groove in the block. Don’t force it if it won’t slide in; pull it out and try again at a different
angle. The pin will snap into place when properly guided in and seated.
