The 1199 dash conversion......plenty of discussion before.
- You will have a full time engine check light that can't be reset or fix or any solution found at this point in time. (Software error between the 1199 Dash and the 899 ECU/DDS)
- Everything else will work
- very early models of the 1199 dash had problems with the turn signals, which require to install a Ducati relay loom to fix it.
- source a Base model Dash.
- Odometer will be mismatched unless you take into dealership.
as for cost, depends weather you want a new dash or can find one second hand.
