Backup Light Diagram question

Hello. I have a 1998 Chrysler T&C LXi. I'm wondering if anyone knows what the w. EAT or W/O EAT means in the wiring diagram of Haynes manual on page 12-38? Thanks.

Electronic Automatic Transmissions. The 4spd transaxle is computer controlled. 3 spd is not.

what is the computer box on the inside of the right fender well inside engine compartment? Is this the ABS module or is the ABS module mounted under the HCU?

Is this what you're looking at: http://ww2.justanswer.com/uploads/brownjeff/2010-02-10_171859_8.gif The PCM is between the fender and the PDC (fuse box)

That .gif file you sent seems to be for the PCM on left fender well. I found out what I'm looking for. The TCM is on Right fender well.
