Re:

Installing the Power On Harness on an ECS Motherboard

The Power-On Harness (SA0356-01) will be located in the corner of the motherboard closest to the
CMOS battery.  See Figure 1 for location and Figure 2 for a detail of the harness.

The harness must be connected in a certain manner in order to function properly.  When installed, the
wire on the J2 connector must be closest to the CMOS battery.  The wire on the Panel 1 connector must
match up with PIN 22 on the Panel 1 connector on the motherboard (on the side furthest from the edge of
the board).  See Figure 3 for connector locations; Figure 4 shows the installed Power-On Harness.
