Question:

I have just bought a mahindra tractor and it has a receptical for a 7 way round pin connector. I am just hooking up some lighting and a 4 way standard trailer connector. Do you carry an adapter to go from the 7 round pin connector to a standard 4 flat. It would be nice if it had about 2 ft or so of pigtail wiring. Thank you

I would be happy to help you make a 7-way round to 4-way flat adapter, but there is not one already made. The adapter # 118710 you were looking at is for European 7-way round connectors which is not what you would have on your Mahindra tractor.

Instead you will need to get the 7-way round connector # PK11700 and the 4-way connector # C58044.

You will wire the white white of the 4-way to the 12 o'clock pin on the 7-way, connect the brown wire of the 4-way connector to the 2 o'clock pin on the 7-way, connect the green wire of the 4-way to the 5 o'clock pin of the 7-way, and lastly connect the yellow wire of the 4-way to the 7 o'clock pin of the 7-way.

This 4-way connector is 60" long but can be cut down to however long you would like it to be.

I included videos of the products mentioned along with a wiring diagram of the 7-way round connector for you to take a look at.
