Just in case anyone is remotely interested, I posted yesterday about the failure of my ARB compressor relay. I got no replies so I guess this isn't a common failure. At any rate, at Carquest I was able to get an exact match-part #RY-48 Relay. The one from Carquest is made in the USA not Korea like the ARB. It also seems heavier and better made. The pins match up exactly so no re-wiring is needed. I mainly posted this so in the future someone can search the archives and find the part #.
