Well, wiring the compressor is nothing complicated. It has to be hooked up to the Spike relay. The only thing is you have to take out the yellow fuse in the middle of spike and put the 20 AMP circuit breaker instead (just like the ones you use on the power distributing panel). Then red goes to M+ and black goes to M-, I think you figured that out by yourself. Then the Spike has to be powered through the other 20 AMP breaker that you put into the power distibution panel. Also don't forget to plug the PWM cable into the Spike, so it gets the commands from the RC.
Hope this is helpful.
