OK! Everybody found my problem after about 10hrs chasing wires. Sometime are another my neighbor said his son in-law put a ignition switch down on under the column and one of the wire came out . He said the truck sets for weeks and he never drives it.
So I found the orange wire on the switch someone put it in the wrong hole(see the org wire feed the fuse box where the brake fuse is that feed the 12volts to the speed buffer brown wire. Now just have to take 1/2 day to put everything back together. Thanks for all your info
