I would like to lubricate my speedometer cable (85-Z28 manual transmission). Shop manual states:
"On models without cruise control, disconnect the speedometer cable strap at the power brake booster."
Where is this strap? I can't find it anywhere on the brake booster. What does it look like...is it the rubber plug that goes into the firewall?
Is necessary to disconnect this strap?
Any tips would be appreciated.
