I had several challenges now. One of which is that the wires from the Lulzbot Taz 5 box were too short to wire to the new SKR board. Another is that the RAMBo board used a different connector than the SKR. Lastly is that I didn't want to re-pin the entire connector.

The answer is to make extension/adapter leads to go from the Lulzbot connectors to the SKR connects AND lengthen the wires.

Stepper extenders, End Stop Extenders, Temperature sensor extenders. Using some headers as Male to Male adapters I was able to connect everything up nice and neat. Everything should fit where I expect and I am able to test each connection.
