W-T ground mod clarification early 98.5 alternator

Hi all...I am getting ready to do the W-T ground mod and have a few questions.  I have an early model 1998.5 and the alternator is wired a bit different from the later models.  I was able to find a picture of the connections from a member on here and also a wiring diagram of the alternator. 

 

Do I remove the B+ cable on both sides of the junction block all the way to the PDC or just where I placed the red arrow? Then do I run a new short  B+ cable from the alternator, with 140 amp fuse, to the passenger side positive battery terminal?  Is everything the same for the grounding mod after this point?

 

Thanks for the help!

The B terminal will no longer go to the PDC box. If you’re running a stock amp alternator it should run to a 150 amp breaker or fuse then to the passenger side battery. I have an ‘02 but by going by the diagram that is how I’d do it.
