swapping a auto for a 5spd on obdII

ok i am swaping the svx engine into a impreza with manual trans. my question is for OBDII and the auto trans.
does anyone know if the Check engine light with come on if there is no tcm, and if so does anyone know if i add a resistor to 1 of the 4 wires will act as a tcm, or does anyone have an idea? (no getting an svx is not an option)

Im not sure how many more time you are going to ask but this is damn sure the last time I will tell you.... NO... **** NO.

The ECU and TCU communicate via a data link... "They speak to eachother in pulsewaves" No resistor or other hodgepodge crap is going to work.

Use an auto trans, reprogram the first OBDII ECU to stop looking for the TCU, or go suck eggs

id listen to tom... only based on the fact that eggs are high in cholesterol... and we dont want that now do we?

there are prob 4 threads from him asking the same thing... How many times do you need the same answer?

yea there is 4 or more threads, but until i can figure it out i am going to keep asking,
plus there isn't anyone to reprogram OBDII ecu's. i looked. i was told that the resistor might work.

its a datalink, not a resistance check. Unless you can find out what frequency they chat at and design a control module to emit the proper pulse-waves when they are needed, it is not gonna happen... Just because you keep asking doesn't mean the answer you want is going to jump up and bite you in the ass.
