Outer Limits 4x4 Board

I just did a cab swap and it's all running fine bar a few things I have
the charge,timing belt and brake light on and after the drive back to
my house abuot 10 min it wouldn't turn off with the key I had to stall
it I'm just trying to figure it out and wondering if any1 knows why it
doing it

Fuel cut solenoid?

was the new cab also a diesel?
The fuel cut solenoid works by opening when there is 12v positive present.
Therefore it closes when no power is supplied.
So either a switch is broken and wont turn off or you have done some wrong wiring in the engine bay or the ignition loom.

Yer it was a diesel but it was a bear cab I took all
my stuff out of the old cab and into the new cab

either engine fuse 10amp or the fuel cut solinoid has failed
test the wire that goes to the fuel cut it will have power when on and no power when off if that is good the fuel cut is the problem
