Use this plug and play adapter if you have up to two solenoids to operate that have existing 2 pin Deutsch receptacles and you need to connect to your 14 pin connector on your machine.  This ingenious jumper features special 2 pin plugs that have an embedded LED in the plug so that it gives you an indication immediately that everything is connected perfectly.

It comes pinned out for the most popular machines around including Kubota, Gehl, Cat D-Series, old Bobcat (14 Pin), Takeuchi, New Holland.  For John Deere, there is an internal jumper that you would simply remove the shrink tubing and install it into the A slot.  For High Flow Cat D-Series, you can use this same jumper and install it in either slot N or K so you can turn on your high flow.
