Throttle Position Sensor Wiring
Upon installing my latest mod, i was required to use a different type of throttle position sensor, so i had to splice in a new connector on the harness side. Simple enough. So i took a look at the wiring diagram and it seemed simple enough. Here is what i have to work with so far. This is a view of the new throttle position connector next to the stock honda wiring diagram.
So this is the way i figured it should be wired up.
Now, when i run the car at closed throttle hondalogger states im at 95% throttle, as i rev, the number drops in percentage. So basically, somethings backwards. But looking at the diagram i dont see what it could be. Any help is appreciated, thanks.

Using a DVOM i measured the voltage at the ecu and where i should be getting .45v at closed throttle, im getting near reference voltage, right around 4.6v. As i depress the throttle, the voltage drops to around 1.3v. Thats the opposite of what it should be doing! If i accidentally switched the ground and +5v wires, would this be a symptom?

Ok, just got done and thats what it was. I reversed the + & - cuz i was looking at the diagram upside down, so to speak. Now it reads right where it should. What a rookie!
