Im working on my harness for my 76 scottsdale ( donor 90 1500 4x4) ive been removing all the uneeded wires and connectors and im down to a few last questions ?

The fuel pump relay has a red wire with a white stripe my book says its a fuel pump prime how and where do i hook it to ?

The transfer case is a np241 has a purple wire with white stripe and a solid yellow wire together on a plug are these vss wires and if so do they get re wired to the brown vss wire ( pin a A10 on the pcm) or are they something else ?

pcm pin # C9 is a purple wire book says its a crank wire ? is it needed where does it go ?

pcm pin #B10 is a orange wire with a black stripe book says park neutral switch do i need to hook this to anything ?

Thanks in advance for the help !!!
