Hello everyone, I’m not sure if this is the right place to post, so feel free to let me know if I should open a new topic.

I have a Caterpillar 289D, serial number TAW05718, and I recently purchased a Simex PL5020.

On the Caterpillar, I have a 9-pin connector. On the asphalt planer, there are 12 wires (11 white and 1 black). One of them is for the water pump (I could run that separately with its own switch if needed).

My question is: how should I connect the planer to the machine? Is it possible to have all functions controlled through the joystick?

Also, for my model, should I connect pin K to B or pin N to B in order to activate the high flow function?

Any help or guidance would be greatly appreciated.
