Hi one more time mates. All problems solved. I start from the beggining like friend AMartins said and the last problem was the directions switches, in 1X13 i need to close circuit between pin 6, 13 and 20. only have voltage in 20 and 13 so one of the direction switches was faulty but I need to change both because when i'm testing the truck turning all wheels to the side of the old sensor the error comes. Summarizing this truck have a lot of problems since wire problems in a lot of places, all the 3 temperatures sensors from motors faulty and the one from the hydraulic motor was sending 80v to other components, new display, traction and hydraulic controller, power module of traction and a lot of hours spent... but now is working well. Thanks to all who helped, I'm really grateful.
