Sir this lift does have a cabin relay that is located in bezel with key switch. But if truck always comes on, cabin relay is good. Possibly you had a stuck or welded tip that freed up when you were wiggling wires. If truck acts again, check tips and as i mentioned before, remove the forward-n-reverse swith and take out the 4 phillip headed screws. Inside you will find leaf contacts. Check for cracks in leafs or metallic flake bridge on leafs. Also the throttle may be not returning all the way. These trucks have a throttle module that can be a real pain to set up if tinkered with and not familiar with it. I do not suggest adjusting anything in them unless you have set one up before.
