Decided to install oil pressure and voltage gauges on the X340, used the 1 1/2" gauges from Autozone which some of the other members have used. a little nerve racking trying to make sure the holes are centered but I think they came out pretty good. The big surprise was thought I would check the low oil pressure switch which came on the engine, unplugged the wire with the engine running & nothing happened, added a pigtail wire to short to ground and nothing happened, traced the wire to other side of engine and unplugged the wire connection block and low & behold no wire coming out the other side to the harness. This pressure switch and wire is a useless install, I need to check with my dealer and see if something is amiss or if this is just installed during assembly for use on bigger machines. This is the FH721V 25hp engine. Do any of you have this pressure switch with wire going nowhere on there X340's? Sorry for the long post.
