her are the wire by color and function from DME to throttle connector for 2001 pinout;

pin 1 = BRN/VIO => DME (sensor signal) pin 19
pin 2 = BRN/BLU => DME (sensor signal) pin 10
pin 3 = BRN/WHT => DME (throttle positive) pin 7
pin 4 = GRY/WHT => DME (throttle signal) pin 43
pin 5 = BRN/GRY => DME (throttle ground) pin 20
pin 6 = BRN/WHT {really BRN/BLK} => DME (throttle actuator) pin 44


How do these wire connect to the throttle body connector itself? Cant really go by the numbers inside the connector? Right?

I have check pin 3 with ground (on the car chassity) and i have 5 v with key on. Also checked pin 3 and pin 5 and got 5 v. So looks like i got ground and voltage coming from DME.


How do i go about checking for signal? If the throttle plate moves the resistance should raise or go lower?

you have to go by the colors. The function is the same based on the colors:

cable		intake
1 brn/vio	1 brn/vio
2 brn/wht	3 gry/wht
3 gry/wht	4 brn/blu
4 brn/blu	2 brn/wht (sensor)
5 brn/wht	6 brn/gry
6 brn/gry	5 brn/wht (motor)

there are two brown/white grounds one for the motor one for the sensors. the sensor one is on 2/3 and the motor one is on 5/6 keep them marked separately put tape on one of them to keep them separate.

cut all but the violet striped wire and splice them as shown above.

You should be able to confirm the two sensor leads by measuring Ω from brn/wht to brn/vio and brn/blu and move the throttle plate.
