- Disconnect the AMPSeal 34-pin connector at the front/head of the controller to disable its operation.

Perform this operation as gently as possible, since the bolts conduct full powertrain current and are torqued low-spec at 12ft-lbs. - Immediately cover the cable leads in a strong insulative sleeve to ensure that nothing conductive contacts them.
- Consider arc-over risks beyond simple contact if the system were energized for any reason.
- Warning:
