Well heres the story.

My truck has a ppe tuner, I de tuned the truck back to stock took it out.

It also has an edge evoLution??

I plug the harness in under the hood to all the correct plugs.

Everything is in and tight.

When I turn the key to the ON position, the edge does not light up or anything.

I try to start the truck and it won't start :confused:

I plug in the stock harness and it starts right up.

I strictly want to use the tuner for temps only. I'm not trying to throw the transmission out of the truck.

Is there something I should look for? Or the actual unit is probably shot?

Thanks!!
