Good day, first post here, hopefully correct place to post, first off my truck 2014 5.7 1500 4x4, tree fell on my cab, found donor cab 2013, swapped out every bit of wiring harness and modules, dash, bcm, rfh, ignition, tipm,from my original cab, literally only used the bare 2013 cab, was running with no errors previoulsy, get the swap done, had a few warning errors on the dash, adressed most of them, at a point where everything has power, doorlocks, radio, alarm, speedo, everything is working, here is were my problem starts, have a flashing security light on and 2 errors on the speedo, one sayes service power steering, and other one is service electric throttle control, turn the fob in the ignition and nothing, had a mobile lock smith come out said fob and everything was good, but there is no communication to the bcm or rfh module, at this point scratching my head changed various senors, negative sensor on ground wire, tried new battery, checked and cleaned the accessable grounds, i just keep thinking there has to be a common link between service power steering, and service electric throttle control and the security light, any ideas would be great, dont wanan go to the dealer and start changing modules since it was running fine
