'06 '07 '08 TBSS RPM and TP signal schematics and pinouts

I could have used this about a week ago. Everything worked out though after some searching

very nice documentation. It sure would be nice if the DashHawk or Aeroforce could output the signals to limit the running of wire.

good job Jay .

someone make a sticky!

Thanks guys, in case you haven't picked it up in the schematics, you can actually get the TP signal from the throttle body harness (which most everyone knows) but you can also get the RPM signal from behind the instrument cluster at the instrument cluster connector instead of at the ECM if you wanted. You could also use that same RPM signal if you were adding an aftermarket tach.

Damn, I coulda used that about 2 months ago. Nice Job Jay!

Thanks Jay. Will be helpful very soon.

Not that I plan to spray. LOL

I know its not a schematic, but if you guys need any wiring diagrams for installing any kits or wiring advice just shoot me over a PM. Or if you're a little bit hesitant about installing nitrous on your own, and you want to look over some install instructions please let me know and I can email them to you. We pride ourselves on having the best install instructions out there! Thanks.

It appears the only place to pull a TPS signal is the line that runs from throttle body to the ECM which is basically at front of motor. I see the tach signal is available inside at the cluster but I dont see any reason to look for it there if I have to get TPS anyway.

So think I will just cut into the harness(s) and solder and shrink wrap a couple wires and connect to an environmental connector and plug into that.

Is everyone (06) getting their RPM and TPS signal up front?

Thanks again Jay. Very helpful.

I picked my RPM wire at fuel injector. Not the pink wire, the other wire, any fuel injector will work.

This is another reason I enjoy this site ..Thanks
