Pins #1 and #5 should be connected with wires, however for the pins that connect to the 8
pin chip on the main board (#2, #3, #4 and #8) it's possible to either connect them with
wires or to "piggy-back" the mod. chip on top of the 8 pin chip on the board. If you
connect all the pins with wires then the mod. chip must be wrapped in insulation tape and
secured in a safe position, so the "piggy-back" option is quicker and only requires 2 wires
for pins #1 and #5.
To "piggy-back" the mod. chip, bend pins #2, #3, #4 and #8 inwards against the body of
the mod. chip and then #3, #4 and #8 as shown below. Trim pins #1 and #5 and
trim/remove the unused pins #6 and #7.
Bend the pins into position and then hold it against the chip on the board to make sure
they are lined up correctly. Once all the pins are lined up solder pin #8 first, then you can
carefully position the mod. chip by rotating it slightly and solder pins #2, #3 and #4.
