Just got my little Ranger home from my buddy's shop; new timing, serpentine belts, crank position sensor and spark control module installed. He could not figure out where the computer is located; he was going to install a tach for me, but couldn't locate the brain box.

Any help would be appreciated!

 

The 93 PCM is under the hood on the far left (driver side) in the firewall. Look for a long 60-pin connector.

 

Thanks for the quick feedback; I'll have a look as soon as I get my day's work out of the way.
