So ive tried leaving the red plug, unplugged hasent worked, I have to unit at version 71.28 as needed. So ive got it past the immobilizer part, plugged everything in used first key red and blue are on and yellow is on when the first key is in, second key goes in no yellow light this time, back to first key, still only red and blue on. no blinks just solid from the start. door locks cycle but thats it. ive checked my CAN high and CAN low connections, changed then and soldered them. ive checked my door pin wires A18,A17, there soldered to now. but still no luck now ive ran my parking light to behind my light swich controls so i could avoid have to do all the relay crap but thats the only part ive altered. now it did work in my 2016 f350 so i dont understand what is goin on! any help is much appreciated!
