Diodes have not been required on Spikes for several years. You should have the two blacks running to the ground on your circuit breaker, a red to M+, and a red to M-. Of bigger concern here, though, is that your solenoids aren't even switching manually... hopefully someone with more pneumatics expertise than I can offer some insight.
