[Shotimes] Help with computer code

[Donald Mallinson]

A guy that wants to help me tune my '89 needs to know what the "M/T 
catch code" is for the '89 SHO.

I have a Ford Reman computer in my '89 that was installed about 1993.  
There are no codes on it that I can find.

The computer sticker on the back door frame isn't of any help.  Never 
heard of a "M/T catch code" but maybe some of you have.  If so, do you 
know what it is, or where I could find it?

Thanks!
