All the time: something new. My car has worked for 10 years w/o these parts so I suspect they are unnecessary, but nonetheless would like to find out what they are; what they do; and part numbers if possible.
It is a set of two relays, one larger, one smaller. I suspect it has something to do with some kind of emissions, but that's just a guess.
I believe it was Tom Collitt who discovered them missing on my car at PUB; I went back to my original photos and sure enough they were there. Somehow the restorer saw fit not to replace them.
These are the relays in the photos. One photo is an original from my car in the year 1999 prior to restoration; the other was taken at PUB.
I do indeed appear to have the wires with ends that plug into this assembly, tucked away and unused.
