I just received my TVS from Tomco #13200 and it has 3 ports. I understood we needed 5 or is the other two just the ones that ended up looped?

Good thing I did not win that 5 port plug/tubes on ebay the other day, I dropped out at around $40.

If the 3 port is ok is there a plug or do I just hook up the vacuum lines to the TVS?

I only seem to see a 1, D, and 2 marked near the ports. Anyone hooked up a 3 port in place of a 5 port, I do not recall those numbers, the 5 port had two letter designations I believe.
