My question is.. is there any difference between an auto and manual engine harness? Will an auto ECU and a manual ECU fit the connector on the engine harness just fine? Will there be any modification required? Please help answer my question. Thank you.
The plug(s) on the harness that connect to the are the main differences between the manual and the auto harness. The same ecu will fit either harness (those plugs are identical, regardless of whether its a 6spd or auto).

If you want to modify an auto tranny to adapt to a manual transmission, then yes it would have to be modified - due to the differing transmission connectors.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information?
