Default N55 Flexfuel pinout question - 12-06-2015, 11:40 AM

I am replacing the corroded connectors on my flexfuel harness with some clean ones, but I lost track of the pinout because I forgot to take a picture first

There are two shared pins between the two connectors, but the outside pin of one connector is supposed to go to the JB4 dsub connector, and the other wire is supposed to go to the wire nut with the tmap wires.

Which wire connects to the actual dsub connector on the JB4 and which one goes to the wire nut with the tmap wires? If I had to guess, I would say the wire coming from the connector on the right goes to the actual JB4 connector and the wire on the left goes to the TMAP. But don't feel like risking it. Thanks.

It's covered in the fuel fuel guide. IIRC the male FF pin goes to #21, female (from sensor) to #4.
