Figure 2 ECU Front Panel
The front panel of the ECU box has nine holes of three different sizes, and two locking
screws.
The big hole in the center provides access to internal connectors that line up with the
feedthru connectors of the probe. The six equally-spaced holes, surrounding the big hole,
provide clearance for the six bolt heads on the back of the probe’s feedthru flange.
The two remaining holes (1/4” diameter) line up with the alignment rods of the probe and
assure the correct alignment between the ECU and the Probe during installation.
The locking screws line up with two threaded holes on the back of the feedthru flange,
and are used to lock the ECU box in place.
