Kubota electrical accessory plug

[Hay Dude]

In my Kubota cab tractors, there are 2 plugs for accessories.
1. One is round shaped- 3 prongs, screw on lid.
I have the customer user plug for that one. Easy to figure out.
There's another one. It's a small white plastic block with hot wire in it and what looks to be a ground wire.
Does anyone know where to get the "other side" for that plug to make a neat wiring job?

Also:
Re the round plug. Looks like it has hot, neg, and "key-on hot" wires in it. What's best way to hook up a 2 wire (hot, ground) to the 3 wire harness? Should hot and key hot be hooked together?

Thanks

No. The best way in my opinion would be to put in an inline relay. The batt hot is 25 amps so will need to power what you are running. The acc hot is likely only 5 amp. Using the acc hot to flip a relay powering your equipment from the batt hot also ensures the equipment piece goes off when you cut the key off.

Yeah, do not hook "hot" and "key hot" together.

Which model tractors are you talking about and what exactly are you trying to do?

Should hot and key hot be hooked together?

Seems like that would bypass your key switch ( and all dash lights come "ON")

Focusing on round plug with hot/key-hot/ground.
How would you hook a 2-wire accessory (hot/ground) to it?

Maybe I don't understand the question?

Just hook the gadget to ground and one hot or the other depending on how you want the gadget to behave.

If you want the accessory to turn on anytime (no key) use the hot (and any ground).

If you want the accessory to turn on only when the key is on use the Key-hot (and any ground). The accessory will turn off with key-off.

Yes, I know, but I don't like the 3rd "constant hot" (yellow) wire flipping around loose in the cab. Could make contact with metal, so what I did was crimp a 3 way flat-type trailer plug on the end of the kubota 3 wire assembly. Made the negative terminal the one that has a metal nipple so that wouldnt happen. A foam marker is what I am powering. It only has 2 wires, though. I crimped the other side of the 3 way plug on my foam marker.
I don't think the 5 amp key on side of the 3 way power supply is adequate as the foam marker. It appears to be a 10 amp draw. It has a 10 amp fuse in line.
So do I power foam marker 2 wire accessory with 30 amp (red) constant hot or 5 amp (yellow) key on hot?

Your trailer-plug solution, with the exposed prong being the ground, is a good safe way to do it. There is a 2-wire version of the "flat four" trailer plug that may be more suitable. It's referred to as "SAE plug" and will connect to a flat four, but access only one of the 3 sockets.



If you want to switch it with the key there is a fairly simple way to use the 5A switched power by adding a relay, if you want to get into that (it's more involved).

The 10A fuse is a good way to guess the amps draw but not definitive that the foam marker draws more than 5A. There are fairly simple ways to measure the amps draw of the marker, if you have a multimeter that has a 10A connection. If you measure the amps draw and its less than 5A, then you can use the key-hot.

Your current solution seems adequate. What are you trying to improve?

Ended up buying a male lighter plug and crimping it to the 2 foam marker wires. Have in line 10 amp fuse. Wish I could find a lighter plug with a little heavier wiring- like 14 ga., but this one should do. Says it's good to 10 amps.
