upon searching on ebay for an ecu, the unit that I believed was my engine computer was described as the transmission control module (tcm as opposed to ecm) so now Im entirely screwed up as to which one is which, in my 1995 RS theres 2 units under the hood. Am I supposed to check out the one toward the front of the engine bay or towards the firewall?

I still gotta find out what unit Im supposed to check out with the pinout diagram, which I am very thankful for.
