Lq4 wire harness

[raverider]

I am in the middle of reworking my harness to put in my 67 c10. I have a 6.0/4l8e setup out of a 99 chev 2wd. I am following instructions from http://www.lt1swap.com/2000harness.htm but am wondering about a couple of wires not mentioned. They are wires coming from connector c2 that go to the neutral safety switch. There is a pink, 2 light greens, and a yellow, as well as a black. Is this plug supposed to be cut off? The alphanumeric group from connector c2 are: e3, a9, and f11
