Exactly. If you have confirmation of it working (which you saw), it's time to check the connections.
You didn't burn anything out, so it's probably something as simple as a loose connector.

Have you modified the mild to wild that lea customs originally built to work differently for what you are trying to do?? That is provide a - (ground) to pin 2 to close the valves. I will assume you have a + 12 v to pin 4 & - 12 (ground) to pin 1?....Also it appears from Sean's schematic provided that there is a factory jumper on each NPP valve at pins 3&5,being your car was not originally equipped with NPP and I will assume that the harness is not there at each valve by mufflers check and make sure u have that jumper shorting back pins 3& 5 at each valve.

is it possible to put them on where they can get jammed or indexed wrong?
Do both actuators only have 4 pins and are you 100% sure all the actuators are the same part number? Wiring diagram shows 5 pins on the rear actuators, that may be an early revision though.
Are they turning in the right direction to close the valve when you apply power?

If you look at the wiring diagram pin 3 and 5 have a jumper on the NPP valves.
The pictures that were posted in an earlier thread only had 4 pins which are what the front valves show in the wiring diagram.
Just making sure that all the valves are the same like posted earlier, possible the front and rear valves may turn in a different direction.

That's good to know - I knew the M2W ran more than a simple relay, but it's nice to have confirmation.
My 'design' on this was a simple wireless on/off relay, which while it worked, was less reliable than just a simple (fused) wired switch solution. Not rocket science since these are either open or closed.
Neat that the C6 actually was able to control relative position of the blade (like a QTP cutout, etc).

I'm not the OP just trying to help,as I know the maker/creator of the original Mild to Wild device.....I believe the new NPP valves by design are spring loaded in the open position. The CCM on an original equipped c7 with NPP provides a PWM signal to pin 2 to adjust the level of open position. The OP is just trying to use the mild to wild device to simply open & close the NPP valves on a c7 that did not have the OEM option that he has since then added.
If the actuator moves you would think it would close the valve..

and it moves. But like it has short. I got both to move testing but when they on the car they won't.

Looks like it takes a pulse modulation to number 2. With 12v to 4
and ground to 1. By playing with it will turn but not with just 12v.
