The trailer brake controller wires on a 2018 Ford E-450 are blue for brake output, yellow/red or gray/red for 12 volt power, violet/white or yellow/green for stop light, and black/gray or black/violet for ground. These wires will all be located inside a 14 pin grey connector located behind the dash. I understand that you said you have a 2019 Ford E-450 which may be why you were told there is not a plug-in harness available however, the schematics for a 2019 Ford E-450 have not yet been released by Ford as of March 2018. With that being said, you most likely have a 2018 Ford E-450 not a 2019 Ford E-450. The reason for this is that the chassis model year is almost always one year older than the actual motorhome. For example, if you have a 2019 Winnebago Outlook on a Ford E-450, the Ford E-450 chassis was most likely made in 2018.

If you will be using a Tekonsha brake controller such as the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 then the correct plug-in harness for this is the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3034-P. If you have a different brake controller just let me know what that is and I will see if a plug-in harness is available.

I have a 2017 Aspect winnebago with a ford E-450 super duty v-10 gas engine I need to know the color code of the four wires that are under the dashboard above the break pedal that aren’t connected to any thing I don’t have a special harness for this so i need to know which wires go to connect to. Thanks for any help you can give me.

I wasn't able to track down the color coding for the factory brake controller wiring on your E-450. If the wires aren't labeled at all, your best bet will be to test each of them for function with a circuit tester.

Yes, the Plug-In Harness # 3034-P is the correct harness for the 2016 E-450 chassis. You had mentioned having 4 bare wires behind the dash though instead of a plug, so I would just try and verify that the factory plug is in fact present on your chassis to allow for this hookup.
