So I'm replacing my alternator & the 2 pronged wires came out of the grey harness assembly as the alternator fell out of place from removing support bolts. The grey harness has >PBT< on one side the other appears to be ^1 1 The wire colors are Red/Yellow and Black. I would like to think the >PBT< side is Red/Yellow, the "Positive/Battery/Terminal" or some such other acronym. Thank you.
