I bought a cargo lamp switch as an OEM looking switch to power an air compressor. Is there a diagram of how to use the 4 pins on the switch? It appears I may just be able to use C & D, but I'm not sure.

Yep, you can do this by using the drblu/wht (c) wire + and then make your own ground wire. You will then have a 20-amp fuse to work the air compressor. Let us know if you need anything else.
