so i think my wire guy didnt hook up my TPS wires correctly. im not getting power to the plug. anyways there is three colors on the plug. they are:

Purple/pink stripeyellow/blue stripelight green/cant tell the stripe color

anyways i am going to run 2 new wires back to the ECU for power and signal. i have figured out from the FSM that the middle wire which is the yellow wire is the signal. does anyone know which wire, purple or light green is the power wire?

yes please check. yesterday was the first time i got the car on the road and i couldnt give her any gas or she would buck. and she has a high idle (2000-3000rpms) so i thought it may be the TPS. im getting no power to the tps but i get power and a signal at the ecu. so im hoping once i run these new wires, this will help fix the bucking and high idle problem
