Testing And Repairs

Do not use wires or harnesses with broken insulation. Replace them or repair them by wrapping the break with electrical tape.
After installing parts, make sure that no wires are pinched under them.
When using electrical test equipment, follow the manufacturer's instructions.
If possible, insert the remover tool from the wire side (except waterproof connector).
