Can I Put The Ecc In My 93 Se I Have The ***** And What Changes Do I Have To Do???

You need an FSM to compare the differences, no one has yet attempted it to our knowledge.

agreed....i am going to do the swap....there are alot of wires....JUST some of the differences are:

the ECC HU
the HVAC programmer
air mix door actuator
dash wiring
outside ambient temp sensor
the under hood HVAC relay
and the 3-4 various relays that are associated with the wiring....
and there are other things that i am forgetting

if you dont have a parts car harness to do the swap dont even attempt it

IF you end up doing this, make sure you get the replacement components from a 95+ vehicle. If not, you will have waisted alot of time cause now you are at the mercy of the ECC for air diversion. For pre-95 models, knobbies rule!
