    Recent clutch job? Maybe as simple as the wires hooked wrong @ the reverse switch(signal to solenoid on same post as 12v supply from fuse).

    Anything’s possible. I’ve found far more wrong with this truck that I wanted to. The wiring for the lights is hacked up badly.
    I will find the root cause but at least now it functions it just doesn’t automatically lift in reverse. Many thanks.

    Looking at the schematic it is probably like sauerland said and miswired. That is not complicated. I should be able to find that easily. ...should

    I have a 2015 KW t800. I had rapid release leaking air bad. Replaced it the tags works for about 2 weeks. No nothing happens when you throw switches. Factory installed WC tags. Switches light up. Can find fuse or relay. Any ideas.
    Thanks
