Installing my NX Nitrous Window Controller

I tapped the white wire behind the cluster for tack signal. TPS wire is off of the throttle body.

Nitrous Express

We usually have people use the injector wire for tach signal, it is easy to tie into and less noise than a coil pack wire. The TPS signal can be grabbed at the either the purple or green wire at the throttle body.

I'm pretty sure this is the white wire they are talking about

So grabbed the tach from th white wire behind cluster. Set it in 4banger/dist mode which everyone seems to be doing to get the rpm correct. Except my rpm isn't correct. it's off by 100 at idle. and by 2400 rpm the window switch says 3000. soooooooo I dunno what the deal is. tps isn't wired in yet. would that affect it?
