July 18 - July 25
Unwrapped the wiring harness.
Cleaned out unnecessary/unused wiring from the harness. Labeled each sensor plug. Need to extend the harness as the best location for the ECM seems to be under passenger side of front seat. Cut each lead from ECM in a staggered pattern, labeling each end for ECM pin out and destination of the wire.
