Hardware for the following steps can be found in the “Molex Housing and Terminals”
package.
Examine the Molex socket housing. The connector pins insert one way only. As each
connector pin is attached, check for a good crimp. Builders should note that the housing is held
against the PWB-mounted pins by the friction of the connector elements. In order to provide for a
good physical mating, it is recommended that any positions on the header that are not used for
wires be filled with a pin.
– Cut a 23-inch long piece of shielded audio cable. Remove 1-inch of jacket from each end.
Clip off the shield drain wire from one end. Attach Molex pins to the white wire on each
end, and to the remaining shield drain wire.
– Using the end of the audio cable with the shield removed, insert the white wire into
position #3 on a 4-pin Molex header. Insert the connector onto
Conn5
on the right channel
speaker PWB. An additional cable will be installed later on the connector.
– Cut two short pieces of small heat-shrink tubing, each about 3/4-inch long. Place the
tubing at each end of the audio cable. Process.
– Cut a 23-inch long piece of shielded audio cable. Remove 1-inch of jacket from each end.
Clip off the shield drain wire from one end. Attach Molex pins to the white wire on each
end, and to the remaining shield drain wire.
– Using the end of the audio cable with the shield removed, insert the white wire into
position #3 on a 4-pin Molex header. Insert the connector onto
Conn7
on the left channel
speaker PWB. An additional cable will be installed later on the connector.
– Cut two short pieces of small heat-shrink tubing, each about 3/4-inch long. Place the
tubing at each end of the audio cable. Process.
– Route the free ends of the cables toward the front panel using the cable clamps adjacent to
the right channel PWB.
– Collect the shielded audio cables from the speaker PWBs. Route the cables to
CONN401
on the power management expansion PWB. Insert the wires into a 4-pin Molex header as
follows:
