I was hoping for an actual schematic with pin outs in the different connectors so I could verify no issues with the harness.The sender on the tank should have 4 wires. Brown and green pair for level sender to dosing unit. Brown/grey + red/grey to ECU. Is that the sort of info that you wanted?
BTW, while tracking that down I saw a few messages about software updates being needed on some units to avoid false errors on levels, etc. Might be worth checking what's on your controller.
I have not done that yet. Looks like I can get 3 days for 60 bucks.
