Very good.
You push the little button under the T-handle on the shifter, driver's side.
the fuse is in the dash behind the overdrive switch
On the 2000 Ford Focus it is in the right front passengers footwell , behind the kick panel ( there is an access hole )
As far as I know it is located under the air filter box.
remove the kickpanel of the passengers side footwell. The re-set switch is underneath.
The brake light switch is located under the dash. It is connected to the upper arm on the Brake pedal
The overdrive ON / OFF switch is located on the end of your gearshift lever ( P R N etc. )
The overdrive has been switched off , the switch is on your gear selector ( the smaller button that is lower down )
OverDrive Off
unscrew the old one, then screw the new one in..?
No
