When pluging in the data pin to program the led lights fail to come on

Question

installation on ford fusion 2012 no led light on evo

Answer 1

I would check the black 4 pin connector that supplies power to the evo to make sure it goes all the way into the femal connector on the evo it self. I would as well check all of my connections on the t harness to make sure there plugged in and every connector has been fully inserted and is securely conencted
