This is for at least all 2000-2004 Focus models Having a MTX-75 Manual Transmission on your ZETEC powered ZX3 it is: On the top side of the trans, 2 wire black plug, about straight down from the air intake on the bottom of the air box and slightly to the firewall, should be the only plug on the top side of the trans. Remove the air cleaner and battery with tray for easier access. If it is a iB5 Transmission 2.0L SPI SOHC: It is located on the front of the transaxle, next to the selector cable front cover. It is easier to access if you jack up the front left-hand side of the car. If it's an auto I'm not sure.
The switch for the backup light switch for an automatic transmission is located on the transmission where the shifting cable enters the transmission (The side of the transmission closest to the radiator),how about for the manual trans mission models?

You didn't state weather it was an Automatic or Manual transmission. Well any way they are both on the transmission. Manual transmission has a separate switch for the backup lights the automatic is built into the neutral safety switch on the transmission. Automatic switch is about $50.00. Manual switch is about $10.00. Hope you have a manual it is a lot cheaper.
The backup light switch is located on the transmission behind the driver's side front wheel. If the wheel is removed, you can see the switch. It's located directly below the shift cables and is easily accessible with a 17 or 19mm wrench. The plug is a two wire type that has a latch that must be lifted up to remove the plug.
They are usually located down on the side of the transmission.
The backup light switch is located on the left side of the transmission. Disconnect the switch connectors, then unscrew the switch.
Look on the transmission, drivers side, in front of the cross member, toward the top.
The switch is part of the Park and Neutral safety switch for automatic transmission and cost close to $200 dollars, and is located in the transmission close to the shift gear cable. Now if you have a manual transmission then the cost is less money about $20 dollars because is a single switch and is close behind the starter.
