its a large white unit that sits in the drivers footwell once you remove the plastic panel.
it also houses the flasher unit fuse and some others that control hazard lights etc.

\'Wrong information!\'


 It is BLACK and that photo is incorrect....

It is located in the Drivers footwell just up under the back of the dash, and the most obvious clue is, it says F100 on it!

It also looks somehow exactly like this..... :Yawn

Its not the white one fella what i thought was the f100 is in fact something else its CPU 2 not relevant to what you want it houses some fuses hazard lights etc. Sorry:spank

The f100 is located here:
It is the black box, which sits on a small cross beam directly above the accelerator pedal.

It has F100 written on it it also has 3 or 4 connectors going into it.

Remove it give it a clean and reconnect if it needs replacing you should be able to pick one up for £30 ish. Just ask one of the guys breaking their car for one. Alternative look for the electrical manual as it will have trouble shooting steps you will probably require a meter for power readings.

Just to confuse you a little more. This is what I have just removed from an FD im breaking.
 
White one is labeled F100
Black one is F110
 
Are these something Year related?  This FD was a 1993
