A. Locate the factory ECU enclosure. Using a
10mm socket, remove the three retaining
screws. Set the enclosure cover and hard-
ware aside to be reinstalled later. (See Fig.
10-a
.)
B. Disconnect the ECU harness connectors
located next to the ECU. To make room for
the supplied ECU interface, you will need to
remove the plastic connector cradle and dis-
card. (See Fig. 10-b.) Reconnect the harness
connectors. (See Fig. 10-c.)
C. Locate the supplied plug and play harness
connection. (See Fig. 10-d.) Make the appli-
icable ECU connections. Each connector plug
is different from the others so there is only
one possible location for each. (See Fig.
10-e
.)
