You could try looking at the circuit diagrams and see where those two cables go, and then go into that with your two prongs, stick wires into something that's not there might cause damage though, proceed at own risk.

I highlighted 306 because that's the connector people in this thread are splicing into with their switches to activate cruise control. C-227 is where those cables go when they leave from 306.
Have a look midway down this thread to see where the ECM is located. https://mirageforum.com/forum/showth...n-of-ECM/page3
