Volvo VNL D12 auto to manual transmission

We did this ourselves about 2yrs ago. 2014 Vnl, the ishift broke again and they are so costly to repair or replace so we swapped it out with an 18sp eaton. I didn’t feel it was that big of a job. Was a 2 pedal truck so had to purchase the clutch pedal assembly and flywheel, which we grabbed from a truck wrecker for cheap. Did not have to do anything with the wiring harness at all. Once we completed the swap we just had to figure out which wire was the neutral switch, jumper the neutral switch so it would start and drove it to a shop to get the truck programmed to manual vs ishift in the ecm. About a 3 day ordeal. Cost us about a $1000 Canadian, because the ishift is worth quite a bit even as a core the wrecker only needed $500 for everything we needed parts wise and the other $500 went to the shop for programming. Truck has put on 400,000kms plus with no issues. Hope this helps for anyone thinking about doing this conversion.
