Unless your OBD port is broken, you should be able to get codes from the B-1 port. If the resistor has been removed, then your codes will show that.
The ECC 'module' is the dash unit itself. Don't worry about the relay as I have yet to see a dead one.
The resistor for the manual climate control is different from the ECC, so when at the junk yard, make sure the module in the dash is the same as the one in your car.
The only reason to check the codes in B-1 is when the recirc and AC switch lights blink orange about 20 times at start up.
