no both are a 70 pin ecm style plugs. just some of the pins maybe in a different location on the chassis plug. now a bxs 70 pin ecm is different than a mbn with what files they will take. a mxs and nxs ecm is what they call a 120 pin ecm. but a different breed.but same plugs. oh and you cant use a mxs ecm on a mbn for obvious reasons.

One item I forgot to mention.
I replaced my wire harness from firewall to motor side. Old one very ragged and a lot of shorts I had fixed.
Talk about sticker shock (thanks PACCAR)
$1,300
Down side I lost:
Engine Oil Temp
Main Trans Oil Temp
the new harness does not have the wire leads at all....
I was told the new Peterbilts don't have those gauges and that's why!!
IS THIS TRUE?? -
In regards to Jake Brake.
My new MXS "JB" works ten times better than my old BXS.
I also like the back pressure from the "turbos" when "JB" engaged. Again BXS did not do that ... -
Russtrucker.... The ECM plugs are different on the engine side between a mbn and mxs....the truck chassis side are the same.....

Mxs will be fine shouldn't require any pin swaps. Pins 11 and 21 are required on SDP swap.
