I bought a new computer to put in my 1997 protege because I have been having a lot of problems and after replacing several things, everything keeps pointing to the computer. The problem is though I have no idea where the computer is located in the car to replace it and I can't find any info on the internet. Does anyone happen to know where it is? Thanks

 

mazda has typically put them one of 3 places.

1. passenger floor board. there is a panel under the carpet on the passenger's side where they have put it on some models.

2. under the dash. it will be kind of obvious but don't confuse it with any of the other control modules.

3. under the center console. there are very few with them located here, but it will be in the center console in front of the shifter if applicable.

 

Yes, your ECU also called a PCM is located in the center console just ahead of the shifter under all that plastic. You have to take out the center arm rest/junk box first, then the plastic bezel that surounds the shifter.
Di9sconnect your battery before plugging in the new PCM.

 

yah..its underneath of the glove box..see photos.
