I have a 262 from when we had autopilot on our 8410, and a lot of the cabling to go with it.  I want to hook up the 262 in my 4440 and connect to an Integra.  I want to map where I am going to replant soybeans.  What cable do I need to connect?  I went through my inventory and can't find any that work.  I tried using the autopilot harness connected to the 262 and connected to the display harness, but I am thinking the autopilot must have supplied power to the 262, not the display cable.

Any suggestoins?
