I have a 5.3L LS truck motor and a 6L80E transmission that has been swapped into a 55 Chevrolet Pick up truck. The engine and transmission are not from the same truck. I sent the ECM and TCM to Speartech for programming. The ECM came back tied to a 2012 Corvette 6.2L engine.

I have been on the phone with Dakota Digital tech support several times. We have checked all the voltages and resistances per Dakota's specs on multiple occasions. The cruise control powers up, when I attempt to engage the cruise function the green light indicating cruise is on lights up but the cruise does not engage. As soon as the set button for the cruise is released the green cruise light goes out.

Has anyone else had this experience and what was the solution to get the cruise control working.
