I'm not sure exactly what you are talking about but suspect the "3 pin MU" you mention is for Field Loop dynamic brakes, found on earlier GP's. You can think of kind of like the old style Christmas tree lights where if one burned out, the whole string went dead. Early units had separate jumpers for the dynamic brake, and a problem with one could kill the whole consist's db. Later units went to a "potential" type which was activated through the regular MU jumper and did away with the separate recepticles found on older units.

I Know it's for the 2 -3 pin MU for the Brake Control but I need I wiring for is in go to convert to a 27 MU only by hook-up the 24T lead.
