Left over from the T5 swap, I have a 4 prong connection, which I know whas for the TC, but then there is another 2 wire connection that I left hanging. What is that for?

My car was origiinally a 87 v6 700R4 and uses a speedo cable. It does not have a VSS. What should I do with this 2 prong connection? Leave it hang?
