Help with TPS and RPM/Tach wires

Hey guys im trying to wire my dynotune window switch and I need to locate the TPS wire and the RPM/tach wire. I searched it out and came up with (the Dark blue wire, at PCM pin number 12) for the TPS. But what about the RPM wire? I think its suspose to be white.

Remember my cars a 98.

Thanks..

I just wired my nitrous outlet rpm box up this weekend and I also have a 98. Good thing is I already had my pcm tapped for the rpm awhile ago from installing my shift light. You do have the correct pins though. Install university has a write up on installing a shift light which shows the pin for a 98 for the tach and 35 is the one you want. The tps was pretty easy to follow in the harness for me as well, good luck man.
