N55 JB4 Harness A vs B

What exactly is the difference between the A & B harnesses? from pictures all i can see is that the connector for the TMAP is different. I ask because im trying to find a used JB4 and seems like the 'A' harness JB4s are harder to find. If its just the connector then thats a super easy mod
