Hence i use 1 of each for my ems and wire the stock DME's input so that the 4 tps'es it reads are just 2 physical.

My dme supports % slip calculation so i could get my TC from there but im a perfectionist so even if i remove the lights i will know something is not as it should be
Woah!

You might want to look at this:

Those TPS signals by the way are inverse to each other...combining them will either burn something out, or your'll end up with either a 0v or 5v signal depending on which pair you chose.
