Looking to see if anyone has installed the relay (AM107421) on a Deere 330 Garden tractor with the Yanmar 3 cyl engine. I used this on my two diesel Kubotas with success, but don't know if it will fit on this machine.

The symptoms are the classic periodic starting issues. All connections are freshly cleaned, good battery with full charge, etc. I'm convinced this relay is the next thing to try, but would like to know if there are mods folks had to do to the wiring to get it plugged in.
