2. Attachment

 

1) Tighten screws (Ø4 × 10, 2 pcs.) fixing the electric parts box.

2) Connect the connectors as original before being removed in item 1.

3) Perform power supply wiring, remote controller wiring, and crossover wiring between inside and outside.

NOTE)

For drawing of each wire and position of ferrite core, perform wiring same as those before remov- ing. If there is incomplete drawing of wire, short or water leakage of the parts may be caused.
