FICM WIRE HARNESS MISSING PINS?

DOES ANYONE KNOW IF THE WIRING HARNESS FOR A 04 6.0 FICM IS SUPPOSED TO BE MISSING ANY PINS? THE LARGEST OF THE 3 CONNECTORS IS MISSING SEVERAL PINS IN THE FITTING ITSELF. THE OTHER TWO SMALLER CONNECTORS HAVE ALL THE PINS THAT I CAN TELL. I JUST HAD FICM REBUILT TODAY AND THEN RECONNECTED IT AND WONT CRANK BUT TURNS OVER. SHOWING CODES U0306(SOFTWARE INCOMPATIBILITY) U0105(LOST COMMUNICATION) AND U0105 AND PO671. ANYBODY GOT A CLUE ABOUT THE PIN COUNT AND ANY OTHER HELP ON THIS SITUATION?

to start with can you please turn off ur caps?

WONT CRANK BUT TURNS OVER<- this statement is contradictory, the engine is spinning yes or no?

sounds as if the ficm may possibly need to be reflashed, depending on what was replaced

Re: FICM WIRE HARNESS MISSING PINS?

yes, it will spin over but will not crank. if i wouldve kept trying it wouldve burned up the starter. when i had it repaired today they DID have to put a different board in one side of the ficm because they said one of the traces was damaged and unrepairable. this was the side with the capacitors and was told that if this side was replaced, the ficm would not have to be reflashed because the other board was the one that held the memory and the one that was replaced was the voltage converter side... go figure!

Re: FICM WIRE HARNESS MISSING PINS?

it was rebuilt i assume with newer components that needed replacing. same as if it went to swamps or something. sent it in for a redoing because it was showing 31 volts at idle. its the board with the two black caps on top of the capacitors.. it is broken where the two capacitors on one side have two legs each that have to be pushed down a little while u retouch the solder joints.. does that help any?

theres a small board that 3"x4" roughly and the other is the same size as the ficm housing, i do believe they replaced the power side of the board but i think you may need to check into getting it programmed

Re: FICM WIRE HARNESS MISSING PINS?

ive looked for chafed wires and such, no luck. checked fuses and all good. but the codes all pointing towards no communication issues makes me think that also, but i was REASSURED that reprogramming was not necessary and im going to be pissed if it does after the promises... do you know anything about how many female ends( i assume thats what they are called?) are supposed to be in the actual wiring harness (the larger one) itself? the two smaller ones have silver female ends in each hole to accept all pins from the ficm but the largest of the three has several female ends missing from the truck side harness itself. seems odd to me..

Re: FICM WIRE HARNESS MISSING PINS?

Are there wires going to the holes with the missing terminals?
