I know this is a silly question but where is the orginal ground eyelet mounting point for the rear lights on the 400.
Mine was hanging when I got it & still is. Seems fairly short it has to be right there somewhere I just cant see it. I know any ground point will work. Just would like to know where it was from factory.

Now that I got the rear blower mounted I want to put some led headlights back there.

So it is sandwiched between the seat pan & frame bracket?

Here is a picture of where mine is grounded. Mine is a later model 400, 1982 IIRC. I do not see a rubber isolator but I'm sure this seat pan has been on/off many times and I have only had the tractor since MAR 2010.

Any where you ground is going to be fine,when I take a seat pan off I re drill a hole in the frame in the back and sand the paint and put some lube on the spot and ground it there then when I take the pan off next time I don't have to be concerned about the ground.

Ok, I looked up your schematic, 12, 13, 14 are the nut, bolt, and washer. The bolt is upside down and should be coming through the fenderpan/frame bracket and then the washer/nut attach to it. There is a grommet, #16 but that is shown on the left side tail light at the top of your schematic. Not sure what its for, maybe for the hole in the fender pan for the tail lights so the wires do not rub on a sharp metal edge?

That grommet should be for the wires for the seat saftey switch.

The 300 has rubber mounts & when I saw that on the 300 I had thought that maby the 400 used them as well, but apperently not.

If it has a seat safety switch. My 1982 has a seat safety switch, the 1976 I just picked up doesn't have a hole in the seat pan for one, so I am going to assume it didn't come with one. I am not sure when Deere started incorporating safety features like that.
