Started playing with the Stein provided harness that ties the AFS3500 to the GNC 300XL. Seemed pretty straight forward. I had to verify a couple of unlabled wires, but the schematic provided was very well done. I put the connectors on to the appropriate box. I then started routing the remote compass wire - hopefully it will reach the tail where I have the box mounted - we'll see. More to come...
Harness connected. Note the remote compass cable coiled on top.
