Two unknown PCM wires

[Sactodreamer]

I'm working on my LS swap into my 97 with the 4.3. I used the wiring info from lt1swap.Com. He was swapping a 98 with the 4.3 and I know the wiring is a little different so I found the wiring for a 97. Between the two wiring diagram I think I was able to figure most everything except two wiring.

One is a black wire with a white stripe that was in the black plug #12 spot. The other is a purple wire with a white stripe in the black plug #14 spot. The wiring diagrams for the 97 or 98 show these pins in the black plug as empty.

Perhaps a moderator will move this thread to the LSX + Carb Swaps sub-section.

Sorry about that, I figured it was was more the stock wiring harness issue, but I am doing a swap.

Are you sure those wires are from the black plug? All of my purple/white wires were from the blue plug. Either the O2 sensors or the VSS. The black/white wires I had were in the red, white and black plugs.

I have some other complete harness's I can check tomorrow to see if they offer any information.
