Ok, as most you know my motor is in a ford...

That said I am changing my TPS setup to the first gen one. The one that was in there before was ok, but I don't like it and the dodge one will work better for what I need.

Anyway I need to know if I have this right, look at the pictures and verify this for me?

the wiring on my truck has the same setup as that last pic.

5V ref = r/w wire
TCU input (TPS output)= y/bl
ground = b/w

dodge TPS has

violet/white
black/blue
orange/blue

Now according to the diagram for my old dodge in pic 2 and 3 the dodge wiring is this

5V ref = violet/white (right wire in top pic)
TPS output/TCU input = black/blue (left wire in top pic
ground = orange/blue (middle wire in top pic)

Is that right?

 

After some thought and study on the matter I have concluded with 95%certainty that In the pot fix threads it refers to the orange wire as the ref. Voltage but I think what is meant is that it is the signal/output voltage. The violet is the reference voltage aka the supply. Black is ground or return in the case of the last picture.

Can anyone more certain than me verify this? It makes the most sense to me

Set up in said configuration will have zero throttle around 1volt. And wot somewhere above 3.5 or so volts if configured/asjusted right on a first gen

Best get it right. I'm pretty sure the center terminal is the wiper. Hooking it up wrong could smoke something, like the PCU.

Nope.
Orange/blue is the sensor out (wiper)
Violet/White is +5V from PCU
black/blue is ground from K4 splice

 

Yeah that's what I figured after some thought. The orange is the return voltage that the TPS (aka pot) is putting out.
