CAUTION!
The following steps should only be carried out while working at an anti-static workstation (Illustration 1) and wearing a grounding wrist strap.

Position the ECM on the anti-static workmat so that when facing the multiplugs, the red multi-plug is at the upper right and the black multi-plug to
the lower left.

Anti-Tamper screw bit.
