Don't wire the pressure sensor directly in-line with the Spike. The pressure switch (5 amps) isn't rated for the current draw of the new or old compressor (10 amps), or the peak at startup of 25 amps.
That 25 amp startup is also why FIRST recommends that the 20a fuse in the Spike be replaced with a self-resetting 20a breaker.
