Going to refurb my air suspension compressor over the next few weeks with one of the kits, is it worth replacing the relay as well?

I haven't needed to look at the compressor yet but chose to replace the relay last year as a preventive measure rather than have a problem. The relay does have quite a hard life over the years. Better to have piece of mind for the few pounds involved to change it.

Good idea to do the compressor before it goes. Where would one find this relay, may as well do it at the same time?

^ This should help

Thanking you kind Sir
