Hi everyone,
I recently acquired a used JB4 that the seller claimed was Harness B style. Unfortunately it is not, which has led me on a search for someone who wants to trade as I now have Harness A but need Harness B.
I know that BMS will exchange the harness for $250. Being the cheap ass I am, I will be trying to convert it. I believe I have located both male and female replacement connectors and will be trying to swap once items arrive. I believe going from Harness A connector to Harness B connector will require me to "flip flop" the wires from what I can tell in the photos as the pins do not line up in the same position. Stay tuned.
EDIT:
See attached PDF of conversion
