You don't use clutch fluid for a manual transmission vehicle.
I found the owners manual for the 2003 mazda b2300 and it shows the fuses and what they are. http://www.manualowl.com/am/Mazda/2003-B2300/Manual/798
You can find the fuse box diagram for a Mazda b2300 pickup when you do not have the manual by writing or calling the manufacturer for the original manual.
