I have a PWG Board and PWG Harness (Harness A), I have managed to get an email confirmation regarding rebate from BMS for swapping the Boards (this refund has since stopped), but if i get the EWG Board and EWG additional Harness and connect it to the PWG Harness.

Is it much the same as the Full EWG Harness (Harness B) except with the extra un-used plugs/wires and then at a later date convert the PWG harness to the EWG Harness?

Chris,

Your PWG type a harness will not fit m135i as these engines all have type b tmap plug.

If your seller described this jb4 harness as being suitable for f2x n55 car they are wrong, send it back to them as its come from an F1x 5 or 6 series.

This one without EWG Harness but was brand new and USB cable actually sold for £225.

Does yours have the latest board and FF wires etc?
This isnt a for sale post but just for the benefit of the OP IF he is looking to buy one. Unsure if he is selling or buying.
I actually bought this one off esiii, havent fitted it yet. Im looking to sell it as i have change of plans. If the OP is interested drop me a PM. Il hopefully have a proper for sale thread up tomorrow. Just after what i paid, £225 collected or £250 packaged, posted next day recorded and robbing paypal fees covered etc etc.

I have managed to fit the jb4 harness and the stage 1 box (having unused wires tucked away). It seemed like the plugs matched.

Just waiting for the board to be updated really.
