Okay. I have the switch wired, and I'll be fixing the cables momentarily. Now, when I plug in the PWM cable to digital slot 1, I get a message saying +5v Output Low on the RC. Is that because I don't have it grounded?
Also, I have the solenoid wired up right, but now the issue is getting the compressor to act right, because right now it's taking a fourth controller to turn the compressor on, and it only lasts while the trigger is held. What am I doing wrong? Once I fix the switch, will it run correctly? Explain.

I also have to program the trigger to keep the Spike in forward so the pneumatic rod stays extended until I press the trigger a second time. I have a programming thread in which I'm asking how, and I have the responses I think I need, but I need to know where the codes go. It's entitled "A New Programmer". It's the only other thread I have created.
