[R-390] Wire harness

[Robert Newberry]

I should clarify more.

A= red stripe
B= black stripe
C= Orange stripe
D= shield/braid
E= Green stripe
F= Orange stripe
H = White

Possibly someone could look inside theirs and check j214. There should be
an orange stripe wire inside the shield. Could someone confirm what I have
with theirs? I need to confirm pin C and F.

Thank you.
