Handling Connectors
a Make sure the connectors are clean and have no loose
wire terminals.
a Make sure multiple cavity connectots are packed withgrease (except watertight connectors).a All connectors have push-down release type locks.
LOCKII{G TAA
LOCKING TAB
a Some connectors have a clio on their side used to at-
tach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
a Some mounted connectors cannot be disconnected

a Check tor loose retainer and rubber seals.
RETAINER
a The backs of some connectors are oacked with
grease. Add grease if needed. It the grease is contami-
nated, reDlace it.
