You could try a reset on the autoride by removing the positive battery cable and then touching the cable to the negative battery terminal for a few seconds. I'd suggest getting the correct relay first- if the new one has an extra pin it could be completely different internally and you could damage other components. Relays are cheap, get the right one. The other system components are very expensive, hope you didn't damage anything. Good luck. Autoride problems are very challenging. I'm still trying to get the "service ride control" message off after completely replacing the system with Arnott stuff. At least it airs up now.
