Thanks a ton! These were the right numbers and after calling a few local dealers, I found one that had some in stock. Got the connector and 4 terminals all for under $6.If I'm guessing correctly on the connectors on the mulch control wiring harness, the mating connector is T24166 and the wire terminals would be 57M9637 for the yellow wire and 57M7499 for the power wires.
Is it easy to retrofit? It’s a feature I didn’t order, don’t need, and for some reason really want.The 2016+ X300/X500 decks are designed to work with an optional electrically-controlled mulch cover on the discharge opening. You can choose to mulch or not by pressing a button on the dash. Here's the 42" version as an example.
Thanks for the info! I know they offered it to me as an option so I’m going to say I’m a MY18. There’s a hole for the switch for sure.Deere didn't start putting the necessary power connector (discussed here) on the main harness until 2018. If you have a 2016 or 2017, you have to replace the main wiring harness to get that connector and replace a piece of the dash to get the hole for the switch. Once you have the correct power connector and a place to put the switch, you buy the electric mulch kit.
If you want to go back farther than that, then it's going to require a lot of creativity. Aside from the wiring, they changed the decks to "Accel Deep" decks with the other changes on X300/X500 in 2016.
As an alternative, they were pushing a manually-controlled mulch cover in 2016 and 2017. That's still a permanent installation of the discharge cover, but you open and close it with a lever on the deck rather than a button on the dash.
Thanks. When I connected my volt meter previously I didn't have my key with me, but it acted like a ground, so I didn't think about it possibly being switched ignition. I'll run out there again today and remember my key this time, to see if it shows 12v with the key on.Found this?
I have this exact setup and am trying to find the place to plu the 12V into to the "open terminal" at rear of fuse box. Is this where I would plug into (the port attached to the red wire)?I bought my first John Deere this year, a 2020 X380. I plan to plow snow with this and will likely be working in dim or dark conditions during the winter so I am going to install a couple of small LED lamps and strobes (I live on a highway and want to be seen when clearing near the road). There's an unused 4 way connector with three wires in it, located just below the fuse block. I think its for the electric mulch kit. Can I use this to power my lamps? I've tried to find schematics for this connector, but haven't found any unless I want to spend $150 for a service manual. I have a DVOM to check, but it's a safe bet red and black are power and ground.
What's the smaller gauge yellow wire?
What mating connector body and terminals do I need to make this a professional installation? I really don't want to cut my harness up to wire these in if I can get the right connector.

Based on this, you could still wire from the small wire to another switch for extra lights or just have them on whenever the key is on. The switch could then connect to a relay coil with the other coil lead connected to ground. The Red wire could be connected to a relay Common and the NO connected to the lights. Forgot, connect the negative of the lights to the Black wire.Found this?
