. After installing parts, make sure that no wires are
pinched under them.
. When using electrical test equipment, follow the
manufacturer's instructions and those described in
this manual.
. lf possible, insert the probe of the tester from the
wire side (except waterproof connector).
. Seat grommets in their grooves properly.
. Use a probe with a tapered tip.
Refer to the instructions in the Honda Terminal Kit for
identification and replacement of connector termi-
